Well Mr. Holdener. I am one of the tight LSA guyes. :) 2.04" intake valve in a 40.625 CID cylinder = 19.91 CID pr. Inch of valve diameter and calls for a LSA of about 109.5 LSA according to DVs 128 rule. The point of course is getting adequate overlap for the job, right? If we just assume the mild BTR cam has 217/237/114, the overlap is identical to a cam with 217/217/109 ;) That is why it works so well. Its really is a 109 LSA cam, just with a lot of additional exhaust opening timing that confuses almost everybody.

@gearhead7896

I am on the DV train too. Typically, 109 and narrower is spot on for LS engines. Richard hasn't tested a single 109 (some ppl say the TN cam is actually 109) cam to my knowledge, but he has tested several 108s which should get all the torque available. But, all the 108s tested are only ~.550 lift which doesn't take full advantage of the flow of the rec port head. I'm ready for him to test 109 or narrower with at least .600 lift on a rec port ly6.

With $9k in heads, cam, valve train, intake and fuels system and machine work, your junkyard SBE can make 500hp. I think you might be better off with a upgrade rebuild of the short block.

It occurred to me while watching this that at 325 cubic inches, it's very close to the old 327(326.5 cubic inches). At 365 HP stock it is also close to the rating of some of those older HIPO 327's. Mind you it does it with much less compression and a milder cam. Would be interesting to see a comparison. Makes me yearn for an old F-body with a mild 5.3 and a 5 or 6 speed transmission.

Richard, I just found your channel, and I hope you get this. I've got an 07 four-wheel drive, Yukon. I bought it minus the engine. We took a cast iron 5.3 block put a high volume oil pump, one set of top, and one set of side oiler lifters. So there's one tip and one side oiler lifters per cylinder, just to give it a good oil bath. We then added a set of cathedral port 706 aluminum heads, and a 6.0 Corvette cam. We also built it as a DOD delete. The majority of the parts came from Summit. My question is. Did I increase my performance by any real amount? Being as I never knew what it was like before the original engine came out of it. I'm thinking of doing the intake and if I went with the cam you used in this video. What kind of horse power numbers could I achieve? I'm trying to get the best horse power and torque, but try to stay within my configuration. I have Champaign dreams, but live on a baloney budget.

6.0 all day

Just a question y didn't you try a roller rocker with the 799 maby that would get you what you need to get that 500 on a budget for say doesn't have to be a over sized ither because along with a bigger cam the less friction for say the better so going to a roller set up if my thinking on this is right could get you a Lil more rpm out of it and where you using stock valve springs or what

And also could have tried the trailblazer ss intake as well

roller rockers won't add much on a cam that already has sufficient lift. The stock rockers (already roller) are lighter and will run more rpm than full rollers (much heavier).

What's studs or bolts do you use constantly swapping out heads.

How much more would it gain if you changed the piston and ring thickness? You would still maintain reliability but squeeze a bit more.

I’d just like to see how much more you could get reducing as much friction as possible.

Hot Rod Network did a KZread video where they gain ~8hp from going to 5/64" to 1/16" on a very healthy SBC (close or over 500hp). So, probably less than 8hp. I haven't watched the video in a while but, those numbers should be very close. kzread.info/dash/bejne/X2Ztq7mcXd3Ypps.html

I am looking to do something similar and I don’t know very much. I would be willing to mess around with new piston, what would that change and how should I go about it?

what would I change to do what?
