Ooooo! She luvs cold air!!

I'm actually probably closer to 510-515 right now depending on what percentage you use for driveline loss (let's no get started on that again). Either way, you think I could pick up 20-25 chp?

I'm not really the guy to ask. Pete or Marc are the experts. I just pay them for the juice and enjoy the results.

All it takes is $$$$$$

Didn't the 405 cars use a different profile for the cams? Wondering if that would affect the gains you would experience w Pete's cams. We know that Dave J. ( a 94 AB) is in the 430-440 rwhp range, depending on exhaust, w Pete's intake only cams and full porting. BTW, I am
using 15% parasitic loss.

Yeah, I'm not sure about the cam profile difference. Based on 15% loss I'm at 496 chp and I'm pretty sure I'm making more than that. An engine dyno is the only one way to know definitively what the chp is. Otherwise, it's just a guessing game. It doesn't really matter, anyway. The only thing that matters is what it makes at the ground.

My short term goal, like Paul, is 440 whp. Long term, I'd love to see 450 whp. I'm just not sure we can get much more out of a 5.7L. That's monster power out of 350 cubes. I guess we could swap out the pistons, raise the compression to 11.5 or 12.0 to 1 and run high octane fuel. I wonder what that would net? Someone much smarter than I probably already knows.

FV,

We know that a stock block 350 can put out 474+rwhp or
~ 560chp. That's Pete's car.
At consistent 129mph trap speeds, I'd say its a pretty realistic number.

That's ported, relieved, larger tb, no secondaries, sleeved, higher compression but naturally aspirated. There is one fellow, Wayne Hale who you may know, who has one of his three Tennesse Z's with two custom turbos on it which is Way, Way higher than those numbers. If natural aspiration, one thing, forced induction another and higher. Question is: how much is enough? I'd argue for 550-600 chp is more than enough. Got to kepe wheels in contact with the road making progress too.
