I can't help but notice that some idiots give a thumbs down rating on the video. Richard is giving away free testing and tuning advice that can save a builder big $ and time. I'm retired now after 40+ years of this stuff but I still learn something with every video. Thanks Richard!
I agree! He did a aftermarket head test now he needs to do a factory head test with peanut ports, 781's, vortec heads, and maybe some 088's. Do the test with a good street cam like a 224 duration. No need to pic a cam to see where they all max out at.
Although the current chants at sports functions make me happy, a chant that would make me very happy is, Big Bang big block! ‘Clap clap clap clap clap’
I can’t stop laughing. How do you tell a car guy?.. when he makes car noises at a motor or car not running. I do it and my boys do to. Love hearing another do it. I thought I was the only big kid.
I wish BBC engines were cheap in my area at the scrap yards. My local U Pick it charges $750 for a BBC, but a Gen III 5.3 is $450 out the door. So, at least in my area, it’s much cheaper to go LS. Grab a 5.3, clean it up, open the rings, (or what I personally do is re-ring the slugs), add a cam, add a cheap snail, enjoy your 800 or so HP for around $1600. That’s my go to formula lol. I’ve built that exact setup about half a dozen times so far; that’s what funds my grudge car when I break stuff. I can make anywhere from $6500-$11,000 on the side throwing that setup together and then dropping it into a customer supplied chassis. Of course I also do the tuning for them and turn all the wrenches, but they supply everything else for the swap. Literally the only hard components I provide are the engine, ready to run, the turbo system which as I said typically is just a cheap journal bearing unit with a generic A2A and aluminum bead rolled plumbing with standard silicone couplers. I do use quality oil line components though as that is mission critical. But I’ve never had one complaint and the only one that I know of that has had any kind of serious failure was 100% user error on the owner. Some people seem to think all you need to do to make power is create more boost pressure, without any regard to adding more fuel or making adjustments to the tune. Even in that case the old 5.3 was a trooper because it made 3 full 1/4 mile passes before it popped and the guy was running close to 1.5 bar @ 12.8-13.2 afr on 93 octane E10 using the same timing map I setup for the thing when it was hitting a boost peak of .6 bar.
Hey Richard I have always wandered about using nitrous with a stock mechanical pump and or aftermarket mechanical pump. I have only used nitrous with electric pumps.
I would like to see u do a budget ecu video. something like speediono is priced good. Can run up to 8 cylinders in batch fire non sequential injection.
Love the content Richard I want to use this set up in my Gen 6 99 suburban 2500 what would I have to do to keep my fuel injection setup or what’s a good aftermarket fuel injection kit
I ended up finding someone mentioning 454 vortec head flow numbers, but it was only the intake at .550 lift, he said it was 246 cfm. I don't know how much different it would be at .500. 781 heads gain about 12 cfm from .500 to .550. I guess it depends on where the vortecs start falling off at. So maybe that puts them around 235 cfm at .500. That would be about 10 more than the peanut ports. Wish you still had those flow numbers richard😜 just teasing
I've got chance for a running 454 in a motorhome, thing is, I don't know if it's a tall deck or not. How do I tell? Your videos have helped me out tremendously and my next project is a '78 Pontiac Lemans 4dr that I'm building a sleeper out of. I'm pretty sure it's got the peanut port heads on it. My aim is to boost it. Also, do you think the rear dif from a Grand National or G-body Hurst Olds will hold up? It's not going to be anything radical.
Is there a cam that you would recommend for a street strip motor that will still work with stock pistons on the gen vi 454 that would be little more aggressive for a turbo motor Richard holdner?
I know this is an older video just had one question. I have a stock 454 and a 78/75 with a .96ar turbo. You said you can get the same power using that. Wouldn’t there be a lot of back pressure and choke just using the one?
@@richardholdener1727 so I would be better off running two of those turbos. I’m running the same cam as in the video also. 600-700 is what I’m aiming for. Just mostly a fun street car. Strip once in a while. I love you’re videos btw. Super helpful info!
Richard i would like to know about the difference between stock manifolds and header at these low rpm's i don't think the stock exhaust manifolds would hurt performance that much whats your thought???

He does have a video on how he tries to do it for cheap with the piping and everything. He does the same thing over and over with it, he even uses the same turbo/carbs for different set ups.

carb cfm times 3456 divided by cubic inches tells you how many RPMS that carb will allow that motor to operate. so 4,949 Rpms but really more... as that would be at 100% efficient for math problem.

Should be fine, but I would gap them, for the simple reason that you’re gonna wanna more than 9. Lol you say you wont, but you willl!!!

It's big bang time
I don't know richard, it'd be nice to see what a good head upgrade would do to a factory 454 sice it's easier to do a head swap than a cam swap.
a head will do very little without some type of cam, and most will offer a big drop in compression from the stock 102-cc heads

quick fuel most likely
