thats the worst power

If you could make a 383 have 510 cheap enough to sell it with no reserve every guy on here with a 350 would do that in a heart beat. I think its crap, maybe pushing 510 with a nice psi boost or good shot of nos.

Looks kind of nice maybe with a little less red and some polished aluminum it would look really good, purple injectors would have to go though lol.

yeah I seen that the other day.....Way too much red for me.
Hard to see getting that much hp from what looks like a stock runners and plenum....maybe even a stock intake. I think it would have a hard time breathing.
Yeah and purple injectors.......I think that would make the HP #'s alot lower! LOL!!

I busted my gut over the HAND SELECTED CAMSHAFT. This seller is smoking crack if he think he can make that kind of power with stock runners.
I dont think its possible.

Looks sketchy all around, and the paint just looks like he doused each part in gloss candy apple red spraypaint. Like im seriously wondering if that AC clutch is stuck to the actual pulley lol.

He used a 230 intake on a stock TPI

That engine has not been ran. Look at the exhaust ports, clean as a whistle. I wonder what that hand selected cam is.

Yeah, that TQ curve is definitely for an engine equipped with a short length runner setup like an LT-1 intake. he's got WAY too much TQ over too high of the power band for a long tube style intake even if it's got a ton of aftermarket parts on it. I'd think that there'd be real steep drop off of TQ at low RPM even with the best TPI parts if he was running 230CC intake runner heads, can you say lazy ports?

You should e-mail them back and say that they must have sent the wrong dyno slip because its doesnt seem to show 510hp.
