I'd love to see an overlay of the final configuration of each combo...So we could see a direct visual comparison of the torque and horsepower curves each provides.
You’ve answered so many of my questions about my big block build and saved me so much money, time and agony I’m sure. Thank you very much for your time and experience shared.
Dang it man, now I have to find a gen 6 in a junk yard. I’m wrapping up my stroker LS, so I guess it’s time to do a big block! The low end torque of these things is so awesome. Perfect for a street rod.
3:45 Richard on your oil system, add a 1 quart or 2 quart accusump pressure reservoir. This will remove 1 or 2 quarts from the oil pan, to help decrease windage. Thanks for All Your Help!!
@@richardholdener1727 On my car it does. I put 6 quarts in the oil pan, I start the engine. The oil pump moves oil to the engine and the accusump (1 quart). Before I shut the engine off, I close the ball valve between the engine and accusump. Later I check the level in the pan, 5 in the pan & 1 in the accusump. Before I restart the engine (one week later) I open the valve & prelube the engine. Easy way to Lower the oil level in the oil pan to reduce windage, and NOT worry about lack of oil to the crankshaft. Thanks for all your hard work & information. Helped me to build Chevy small block and chevy Big block. Thanks
This makes me feel SO much better about how I'm going for my build. Edelbrock performer rpm kit, forged internals at 8.1 compression, and a holley sniper! Thanks for all your info
I've got to get my $#!+ Together and get my twin gt45s for my 427 LS project. 70 Camaro street strip. Can't happen soon enough. thanks Rich keep testing.
On alot of these great sounding high hp combos like making 200 more hp then most guys he's running such a high rpm, racing cam in some instances that the powerband is very limited and will make for a crappy street car experience. I have known about this technique for many years. It's not worth in in a street car or truck or even boat. Some cams have a power range of about 4500 plus rpm. A 5000 stall converter won't be fun on the street. And from 4000 to 8000 rpm won't be fun to deal with. Bloodviking
Did I miss something but I don’t recall the first motor the 900 hp all motor there was no displacement mentioned. I would think you’d need over 500 civic inches to make 900 hp NA.
Could’ve ran that 565 tunnel ram on pump gas! Probably would’ve picked up another 30-40 hp! I wanna see a test with a 6 or 8-71 on a big block with 0 pounds of boost. I wanna know if the displacement of the blower alone will make hp. Due to it maximizing the engines VE. In your mind it’s added displacement by itself. You think it would make more hp. Even with 0 pressure. 👍
No. The only way it would make 0 boost is if you took the belt off. With the belt on and functioning rotors in the case, even underdriven 40% it would still make 3-5 lbs. But the parasitic drag would eat up 40 or 50 hp.
There's an old rule of thumb that 15 lbs of boost EFFECTIVELY doubles your engine displacement. So a 454 with 15lbs could make it act like 900ci NA. And that "rule" was 40 years ago, before today's killer heads were available.
Rich, how much would that 565 cost, just in parts, for the average Joe with no sponsor? Carrillo rods alone are 2 grand. The cam/lifters at least a grand, the AFR heads 3 grand, Dominators 1000 each, etc, etc. I'm guessing $15k, minimum.
Kinda hard to beat the stock one for off idle torque. That's what they were designed for. I'm sure there's improvements to be made somewhere though. Just not sure anyone is actually making them.

Sure looks easier to make more than 900 hp when u add a bit of boost than it does to make that kind of power naturally aspirated....thats what I am seeing anyhoo....
Nothing looks as Nasty Mean as a big blower does, but I would prefer the NA engine. What that NA engine has that the other do not, is power adder potential. 300 shot on that thing would be the best of both worlds. The boosted engines are risky business if you shoot 300 ponies of nitrous to them. You can, but I wouldn't.
Depends on the tune. Also keep in mind the cooling of the air charge via all that nitrous and fuel. Couple that with an intercooler, and you're pretty safe when it comes to pre-det.

Why so low on the compression? Are you gonna boost it?
@@sstevocamaro yup! Gonna go with the twin turbo set up he's got in the video, maybe push it a tad further
Could build the entire turbo combo for the cost of a Merlin block :p not short block just the block
That NA build had an insane camshaft!
Yeah, I was like; did he just say 300 degrees!!
300 on the exhaust at .050
@@richardholdener1727 like the valves never actually close..
Lol whats the advertised duration? 360° ...?? Lol
I would of liked to see what that 496 with the 6-71 would of produced with E85 maybe even a 8-71.
Yes ,like I said why build an ls when you can have more torque and power for less money
I've got to get my $#!+ Together and get my twin gt45s for my 427 LS project. 70 Camaro street strip. Can't happen soon enough. thanks Rich keep testing.
I’d like to see a factory duration 5.3 cam, but with .620 lift on both sides and a 113lsa
Nice! Can't wait for the Big Bang BBC!
LOVE ALL YOUR VIDEOS, EVEN THOUGH IM NOT AN LS GUY !
perfect-all of the 900+ videos are not on ls motors
🤣🤣🤣🤣
I'd love to see what that 565 would do with a couple turbos on it!
Amazing video presentation 👍

Hey Richard- great stuff as usual. I'm wondering if you've auditioned for host of Hot Rod Garage? Seems like a good fit
PRETTY SURE THEY ALREADY CHOSE A NEW GUY
Love to see the best NA intake for off idle torque 👍

yes they do

6/71 bit old how about the 192 and 250 from the blower shop??

Personally I blame squirrels
we got a live upload
@@JBZ28LS7 😆
Squirrels drive me nuts!
If it's 10.5 1 why use racing fuel
The majority of 454 street engines will see about 475 to 575 hp
How would the drive ability be on the na motor?
Not as good as either of the forced induction builds, to state the obvious 🤷♂️
NOT BUILD AS A DRIVER
Floor it!!!... You're gone!! Drivability seems fine to me!
Yes I'm interested in drivability and mpg is important to me. I'm thinking of a900 na BBC! 🤣🤣
Sure looks easier to make more than 900 hp when u add a bit of boost than it does to make that kind of power naturally aspirated....thats what I am seeing anyhoo....
Yeah, no shit. That's kinda the point of boost.
I mean for big engines like that, it ain't too hard
He must have jetted those dominator carbs way down on that t ram. Way over carberated.
What does FTW mean?
For The Win
👍💪
Rich should have separated each as a separate build. Too confusing.
Note: "middle 4 digit power" suggests around 5000 hp.
WOOOOO WHHHOOOOO!!!!!!! HORSEPOWER!!!
middle 4 digit suggests 1500 hp
Richard gave you a middle digit 🖕🤣🤣

Forced induction loves chemical cooling.
WE MADE OVER 1100 HP ON NITROUS WITH A SINGLE CARB ON THIS MOTOR
Lol you wanna make 1100 hp? Add compression and methanol to that n/a engine! I bet it would get close.
