having tuned and worked on solid lifter engines for decades the methods and regimes are quite simple. You have to have a scheduled maintenance model: check head torque on that schedule and then, check lash. It is really that simple. IF you decide to go with a solid valve train, then accept that you have to have a very well defined maintenance model, period.

You touched on duration specs varying from one MFG to another, this is why looking at the .050" spec is much more informative

I built a 302 engine for my street driven 68 camaro, a 4 speed car . I had a isky roller in it . I never had any problems with the cam or lifters . Roller rockers. Joe Mar girdle ect . The thing I liked was being able to change the lash some to change how the engine responds . . That was a long time ago . I use to buzz it up to 7800 pretty often. About the limit of my dirty track prepped bottom end. As far a limiter yea I run them in my harley with SS lifters . That was a learning experience. Thanks for your videos ..

I doing a 466 CI for my '70 Torino Cobra drag pack car. I'm going to be mostly going to car shows and a little bit of track time, but being that it was an original 429 SCJ motor, I felt that I had to keep it a solid lifter cam. I contacted Oregon Cams and talked to them and they are doing a custom grind that will fit my needs. I made a mistake at first buying the lifters. I bought Howards Cams solid lifters sport max, but it had a warning about using them for the street, so then I purchased their Street Max solid rollers. I have Comp Cams Ultra Pro roller rockers, I was afraid of going with any aluminum ones. I haven't bought the push rods, as I need to figure out my length, but thanks for the advice about the wall thickness. As you have pointed out, I will have to consult with Oregon Cams, as to which springs to go with, as only thinking about the lift. Hopefully once this is all done it will pay off. I do understand that I will have to check the lash, but since it's not a daily driver, I shouldn't have to check it too often because of not putting on many miles. Thanks for all of the good advice!

Excellent info once more. Thanks Andy Cheers

I've been running a COMP XR292R-10 in my street/strip 440 Mopar for seven years. It's a solid roller. So far zero problems. I use Smith Brothers 3/8 pushrods with Crane Gold Race rockers. When I ordered the cam, I called COMP for recommendations and went with what they recommended. My thought at the time was I didn't want to disturb my neighbors with a cam break in and I was worried about lifter/cam failure with a flat tappet cam. No regrets, the car runs great and so far every time I've checked the lash, it was only out .002 at most. Roller cams WORK!

@@ronniewooddell721 Yup. When I built the engine my goal was not to have as much power as possible. I wanted good power but more importantly I wanted reliability and low maintenance and that's exactly what I got. The car weighed 3500# with a full fuel cell and me in it and it ran consistent low 11s @ 120 for years. Plus I only trailered it to the track once. All the other times, and there were many, I drove it to and from the tracks I raced at and had zero break downs. The only problem I ever had was some oil leaks and it turned out my crankcase ventilation was faulty. Once I took care of that, no more troubles.

I fabricated a lifter rev kit for a solid roller camshaft on a Cad 500. Competition Products has a selection. Purpose for the rev kit is to keep the rollers on the lobes to prevent the pounding of the roller and bearings. Its been 6 years since the rev kit was installed. Recent inspection showed no signs of damage or wear. Jones Cams grinds solid roller cams for street use. Look out Big Cadoo!

Good information. I’m a 300 in- line 6 guy just because I like being different/difficult. I had been thinking about a non roller solid cam. But since I’m only spinning 5000-5500. I probably wouldn’t see an advantage?

Solid cam duration specifications are a small mine feild. Generally, SAE duration is the lash +.006 lift = seat to seat duration. Duration at .050" is the same as a Hyd. The lifter rise is .050" no matter what the lash / quietening ramp is.

I agree that more attention needs to be payed when it comes to valve springs. Very few people truly understand those actual requirements especially when considering street use. Resonant Frequency is also an understated thing in any application being it effects the life of all valve train components, sadly, most people dont know it even exists. I too am also an advocate for Smith Brothers Pushrods, an old racer here in my area turned me onto them years ago. They are known for high quality nearly indestructible pushrods and a quick turn around on custom orders. In my day if you had a splayed valve engine like a Cleveland, 385 series or a Big Block Chevy, Smith Brothers was the only way to go. Thank you for all the good content as always

I personally think if you run a solid roller cam shaft at mid to lower RPMs most of the time it will probably be fine , I do believe that they take most of the severe beating at higher RPM and it's street use if you keep the RPM relatively low for normal cruising solid roller cam shaft can last a long time problem is when the roller needles do starting to come apart it's likely to kill the entire engine sadly

Solid roller opening ramp angle is more aggressive than a hydraulic, that’s the main reason for higher RPM capability with a solid cam profile. Usually solid cams will have a lower base circle to get a more aggressive opening and closing ramp angle

I'm rallying around the family with a pocket full of screws. From my 2 piece valve covers. 😁 Those large bore lifters 1.00 plus and names like Crower and Jesel come to mind. In the interest of high rpm valvetrain survival, I'm looking at a different design pushrod. Small end for the lifter then expanding out to 0.750" up to where it has to pass through the head. Then as large as possible up to the rocker. With that diameter, I can reduce wall thickness. It will still have a far stiffer center section. This is where belt driven overhead cams shine. Less mass to fight against in controlling the valves. Weaker springs mean less HP robbing friction and compression resistance against the Cam trying to force it.

I have a Ford 427 in my performance street Mustang. Currently running a .600 lift hydraulic cam, Howard hydraulic roller lifters and Jesel shaft 1.6 rockers. My valve springs are AFR . 650 lift units. Today a friend asked and suggested why i wasn't running solid roller lifters? I didn't think solid lifters were something i could run on the street for 100k miles. I don't want to exceed the OEM 6500 redline. So, my questions are: How often does the lash need to be checked for a daily, street performance engine that will only see 6500 rpm max? Can i continue to use my hydraulic roller cam or should i get a solid roller cam similar to my hydraulic cam? Can i continue to use my .650 valve springs? Do solid roller lifters require lifter oil restriction in the block? Thanks in advance

Right on excellent great advice, couldn’t agree more. One thing you forgot is that crower makes an oversized lifter that is great for street engines. If I am correct it is .940 dia and stock SBF is .875. Not that hard to bore out lifter bores and go larger.

Can you make a video about using solid lifters on a hydraulic cam?

It most assuredly is about more than just the spring pressure. I have built a BB Chevy that achieved another 1,000rpm's over the pre rebuild capabilities of the engine with just a camshaft, lifter and rocker arm upgrade. Additionally all new exhaust valves and a 3 angle grind were added to the mix but the springs all checked out to be essentially within spec. So with a different lobe profile but with the springs already on the heads the new camshaft with .510" lift on all valves gave me approx. 15% more rpm range. Of course the springs were being compressed more with the higher lift but having checked for possible coil bind and finding none all looked good. The same for the stud mount rockers with adequate slot length the old adage once again held true : Attention to detail and clean conditions during engine assembly are vital ingredients. Once in service, camshaft break in and service frequency, ie oil changes, lash adj. are musts.

"Just a camshaft, lifter and rocker arm upgrade", Ya, of course it can pick up rpm, that's the whole damn valvetrain. The interesting thing is when you pick up 500-800 rpm just by replacing springs OR lifters. Way too many crappy lifters out there and poorly matched springs.

Comp cams Xr292r street solid roller tight lash and Isky bushed lifters and comp cams ultra pro magnum rockers...etc. 3k lb 68 mustang th400, 4k stall, 410 gears, all forged steel parts, revs to 7200rpm. Car is a fcking monster. Had 7 years and 4600 miles on motor. Check lash once a year. Car pulls like its on nitrous boost together, and it makes better power and is faster on E85 with efi. Solid roller only way to go cause i always spin over 7k rpm.

Whatever happened to Schubeck lifters? The were the craze 20byears ago and just vanished.

I have a 16 year old built 381 sbs with a comp solid roller cam setup. Dynoed at 511hp 15 years ago. Then it basically sat for 10 years, with idling here and there. Haven't got to re checking my lash. Just got car on the road and got back from a little cruise. Lifters got pretty loud. So I checked my lash. I'll be damned, one was at a staggering 0.111". Lifters or cam are probably wiped out eh? The rockers have a stud girdle and everything was tight. Gona change cam soon. What do you recommend? I'm thinking hrc. Big Mutha Thumpr from comp. I want low power, easy ramp rates, low lift, minimal valve spring pressures. I want lots of duration, and valve over lap. Victor jr heads and intake, 9.8:1, 381 stroker. I want choppy lumpy idle, and rev only to 5000. Purely street driving with lots of idling. No racing at all. It has a 4 speed with 4.11 rear gear and 28.75" tall tires. Thanks

I run a Cam Motion low lash roller in my 406 SBC on the street and road course track days in a 240Z. I see they don't do anything but LS, LT and Hemi stuff now. I started with regular Isky rollers, but switched to the bushed lifters to not have to worry about the needle bearings. Anyway, the Low Lash stuff is how Cam Motion makes solid rollers live on the street.

I have a cam motion low lash solid cam for my 540, 670 ish lift. Interested to see how it will do, i have a set of crower endurance lifters

I ran solid lifters in my Chevy 235 engine put a 261 cam in it A little noisy at first fire but quiet up as it warms up, of course

Hello. I have a question. Would like to overhaul my Ford FE 390 engine. It should be a normal overhaul, just to cruise with it on the road. Should run well and be durable. What do you recommend me? What camshaft and what lifters. Installed with me is the non-adjustable rocker shaft. Does it make sense to switch to roller lifters and what would be necessary to change? Or should I stay original with flat tappet lifter? Thanks a lot Greeting Ulf

I use Smith Brothers all the time, they are 30 minutes away. Sweet.

what about idling on the street? i heard you want a higher idle to get more oil splashing around usually above 1000 RPM

Great timing on this video! I'm considering the switch from a Hyd roller cam to a solid roller in my 377" small block Chevy. Everyone said how far the Hyd roller has come so against my better judgement, I put the Hyd roller in it. It is absolutely out of rpm at 6100 and totally loses control of the valves at 6600.I like the low maintenance but I just don't think the Hyd roller allows me to see the gains I should be seeing with the 210cc intake ports on the Profiler heads. My car is a stick car. At about 620', the car is in 3rd gear and the 6000 rpm shift light is on. If I leave it in 3rd gear, it floats the valves. If I shift, the car does not accelerate again till past the line. Oh the life of a street strip 4 speed car. LOL

Yeah I believe a Solid Roller would really help you out! Because I have seen your situation so many times.. once the valvetrain goes away you are dropping HUGE Amounts of power! It's not uncommon to see 50+HP gain at the very upper rpm ranges sometimes even more.... Thanks for Watching! Andy

@@1320quick do you run power brakes ?? If not, I would strongly recommend considering David Vizards formula for selecting your next cam. Even though you have nice heads on there, a 112° lsa is way off point from his standards when in the context of making maximum Horsepower. Per Vizards math an LSA in the range of 108° would suit you best for maximum Torque and horsepower. But ,that gets tossed out the window if you need the vacuum for power brakes.

Just what I needed to see I was wondering about the solid roller I have would be OK on the street I have a Howard's hydraulic roller in my big block it's a 427 60 over my cam I'd 235x241@50 616 lift I want to go with the comp cams xr292r it's 254x260@50 666 lift I was wanting more rpm and a Lil more hp the cam is good from 3100 to 7200 and I don't need to bring this motor any higher then 7000. I had a lunati cam that was good in the same power rang and the car flew on the street also I'm going to be driving the car mostly on the weekend I hope this will be safe.rick427

Hey Andy although I'm not a Ford fan I am a gearhead and this info applies across the board. Also I know who is mentoring you and that man will be talked about along side Smokey Yunick and Bob Glidden, Carrol Shelby, and all the legends of motorsports and especially engine development. Best heads I've ever ran were done using the information and instructions from DV. Also I have been looking at engine harmonics at high rpm. It's interesting how a properly balanced rotating assembly actually has it's highest harmonic load around 65 to 7k then starts to fall off. You have any info as to why that happens

What do you say about the crane cam 282H06

@unitymotorsports , what is you choice of oil to run on solid roller stuff. I like 5w30 synpower and LAT 5w-30 break in oil. Reall a needle roller bearing subjected to the loads of a typical drag race engine requires the @212*f viscosity of a 50 weight oil to survive at street type rpms but i prefer a quicker flowing oil and a more street friendly lobe profile to keep them alive for street duty.

@Ragnarok1979

Oil viscosity is based off of your main and rod bearing clearances.

Absolutely. Especially at .904 you can get quite aggressive and still run it on the street. A very lightweight package that can outperform most hydraulic roller setups. Needs less pushrod and less spring package too!

Very uplifting info.

You can run solid lifters on a hydraulic cam. My concern with running hydraulic lifters near maximum preload is lifter pumpup. I much prefer running hydraulic lifters near minimum preload.
