Obviously a "race" motor would be wayyyy different than these motors. But these were built for street duty and instant tq at the hit of the skinny pedal.

Nice - but it can be done with 100 less cubes

VGLNTE1

That's the exact ones we are looking at. Lol

PRE-Z06

Oh, was thinking it was "Leavinu" LWA 630rwhp 402 in his C6

LSOHOLIC

IIRC...both of those motors had mild camshafts and IMO a restrictive manifold for the given cubes.

VGLNTE1

I'm a fan of the medium size cam for street cars. I think they are faster.

And ya, any ls intake sucks. I'm trying to get my buddy to buy robz motor. Lol. I've been watching his results for years. He either lies about what they do...which his et and trap back it up, so that can't be, or he knows voodoo, which must be true.

PRAY

You can follow the below. This was built years ago. I sure it would crack 600rw with a FAST 102/NW 100 and a better exhaust. Great street car. All the power was in before 6,000. It trapped as high at 137+. I daily drove it.

The rectangle port heads outperform the cathedral heads.

Anthraxmm

Depending on the combo though of course, like anything else.

VGLNTE1

150 hp to the wheels by just running 85 must be some world record

VGLNTE1

Maybe for peak. Which doesn't mean a whole lot. And this is coming from a guy who has square port heads.

wilkes02C5Z

if you upgrade the fuel system and injectors properly, and have someone that knows how to tune E85, you will see an average of 20-25% power increase.Note that it was a max effort pull, not the way it sits as a DD, it's backed off a bit. So this is well within the normal E85 realm.However, it is very hard to come by where I live currently so pump gas makes more sense.

I'd do a 440", RHS aluminum block with a Callie's billet crank/rods. 12.0-1 comp, Mast 285 heads with stainless hollow stem intake valves and inconel exhaust valves. Custom ground HYD roller with Morel lifters. On a tight budget I'd run a Fast 102/102 but on a baller budget I'd get a Wilson sheet metal intake...(with a fogger Ofcourse). 2" headers/3" x pipe. Spin it to 7200-7500.. Plenty to go into the 9s with..

I figure this combo would make an honest 650 rwhp NA, then throw a 300hp on top..

$20k budget for parts could easily build this..

Hey this is the motor I had in my C5Z I purchased from PRAY. This combo flat out worked. C5Z Fast List #3 & 4. Should have been #2 spot

robz

I'd buy my 388ci motor for $15K since its proven on dyno, street, and strip.
Add a Harrop ITB to make it perfectly streetable.
Put the left over $2500 in the bank.

Now you have a solid performing street strip monster that you can occasionally spin to 8500+ rpms for half the price it would cost to build from scratch.
