Exactly! And with low compression you can advance more! 👍

I love the big block. Thanks for the refresher course, brother.

That was a FANTASTIC video! Brief, quick, to the point. I loved it! Subbed!

Disagree about the peanuts dropping off after 4500 rpm. I have a 454(461) .030. And howards Big Mama Rattler cam. Opened up bowl blend. Polished intake ports. (Everything done with a dremel). Cut valve guides for new dual srings and viton seals. Full roller rockers.8.5 compression true flat tops(no small dish in center). RPM air gap. 1" phenolic spacer. Holley ultra 800cfm. Engine pulls to 6000 easily and makes tons of power. Massive torque! Velocity= rate of speed!

Hell yeah buddy! 454 with 781 heads right here!

Exactly the kind of info I've been looking for! You rock!

Awesome video man, thanks for the help. Definitely will be following

The difference in power you have seen comes from more than just headers and intake. The air filter and housing, accessories, and the engine temperature it was tested at.

I really like your videos. Good info and right to the point.

This is so helpful! Any chance of showing us what it took to install and run the sniper?

Awesome video .. just installed a peanut port ( 360 casting ) 454 ( gen IV ) in my 85 Monte SS today.. 270H magnum cam and 2" super comp headers. This set up was in a running G-body Elky that i bought as a doner car. I got a CK built 2004r backing with 2400 stall and a GN rear with 3.73s this thing should be lots of fun even with the 8:1 CR

Been running a BBC in my '71 F-250 highboy since 1979.

Diggin them Pit Vipers my man

Hey there...new subscriber here. Do you know where I can find examples of Gen 4 454 builds? It would be awesome to see what people have successfully done to their 454's. I am trying to not mess up my build!

I am using 781's right now, but 290's will make well over 500hp with just a little work anyone can do! They are a great head if you are running flat top pistons. Hell, peanut ports will make 500hp as they sit, and might be the best bang for someone who doesn't want to put in a ton of work. I'm using the 781's with stock valve size, and stainless race valves, on my .030 over 427 bbc. Cam is a Howards 121861-10. 11.66:1 compression, RPM Air Gap, Holley 850 dp, 1-7/8" primaries into a 3" collector that's 18" long. Corrected dyno numbers are 554hp from 5500-6000rpm, and 564lb ft trq from 4500-5000 rpm. Actual numbers for 92 degrees, 60% humidity, and at 1089 feet above sea level are: 504hp from 5500-6000rpm, and torque was at 513 from 4500-5000 rpm. Plenty of power to put my 2962lbs (with driver) S10 drag truck into the mid 10's in the 1/4 and the mid 6's in the 1/8, which is all I'm looking for. Long live big blocks!! 💪👍

@antilaw9911

Peanut ports are better up to certain cam limit. Per cam used, they will take better advantage of the cam rpm range and have more velocity through that range. That equals better throttle response etc. Sure, big gigantic ports make bigger peak power but lose much percentage of velocity for the trade off of low end response. In our minds yes, the big ports look and seem appealing but the reality of how they work goes against conventional thinking. VELOCITY= RATE OF SPEED! 👍

If you're on a budget just stick with the stock valves in your oval port heads. They should be 2.06 intakes and 1.72 exhausts. You'll only be leaving 25-50 horsepower on the table. But, you'll save nearly $850 that you'd lay out to open up the valves and replace the parts. If you want to do some of the most amazing burnouts ever...go with peanut ports. You'll have a blast!

Your videos are awesome. How would a 1986 le8 454 with factor flat top pistons do with 718 heads and a 268cam? It’s in a truck, so I’m looking for torque. The peanut port and the 718 are both 118cc, correct??

@RatMaro

Жыл бұрын

It should work great with that cam and head combination! Flat tops can cost a bit of compression, however if you do have the heads off running a steel shim headgasket can raise compression to make more use of the larger camshaft. Even without the steel shim headgasket the combination should work great though.

Question what crosses the line if you have a 1973 C3 Big Block Corvette and you want more power but want the numbers to remain true to the original build? I know there are many implied limitations and you have to first make the assessment the car is really worth saving or claiming it is a survivor. Does a low profile manifold or different heads, headers, carb cause the car to be truly molested? I'm not looking for a track experience or street racing but just some pleasing pulls and jealous looks.

You forgot to mention upgrading your springs in your head if you upgrade your cam

I have a 95 454 in my winnebago I need pulling power or low end torch my question is blower or turbo

COOL

Got peanut ports... move to large ovals for 50+hp/tq rather than opening up the peanuts. Most 781s have closer to 113cc chambers but be careful with upgrading valves and >.500 lift. If you don't blend the bowls properly you will have huge power losses and the factory valves will actually outflow them

BBC guys take note....if you want the best cam Call Straub Technologies and Tell Chris your combo and he will spec you a cam that will be right the first time and make big torque. People that know won’t tell you because that’s their edge! With oval port heads, Straub cam and 750 Holley and 40* total timing your at 500+ HP!

Good videos man .. I just came across searching for 454 builds 👊😉 Do you recommend to bore if I plan to maybe boost in the future? Just for street looks not for track

@RatMaro

Жыл бұрын

Boring the block is fine, 454s have a thick cylinder wall and can be bored 0.100-0.125. However there isn't all that much performance gain just from boring the block, I personally like to leave them alone unless it needs an over bore to clean the cylinders up. Or if you want to just run a light over bore of 30-60 thousandths. But yeah you should not have issues so long as you don't max out the cylinder with an overbore.

That engine would likely have a Carb versus fuel injection. So someone would have to tune the carb to match. If you did these mods I'd probably go with an 850cfm Holley. But yeah these mods are doable, but they are a little on the harder side to accomplish. Headers and intake are pretty easy, heads and cam are a bit harder.

how much total timing do you run on that stock cam 454 with the headers etc.? I have a ‘78 dished piston 454 with peanut port heads and a single plane that came on the engine when i bought it- I cut the valve guides, put a ZZ502 cam, and isky 8005-A springs and trying to get timing right on. It is locked out.

I see you watch Richard holdener. A little FYI for you, the headers on a factory big block chevy isn't going to give a 30 or 40 hp gain, the camshaft isn't big enough is the reason why. It's not because of the compression either.
