New 357 dyno numbers..

415hp/369.8tq

It pulled over 400hp all the way from 5800 to the 7100rpm limiter.

Was a little lean up top so it could use some tuning.
That was on a first attemp mail order tune.

Forged 357
P&P stock heads
245/254 .598/.605 112LSA
And all the other stuff except for a stock TB..

Re: New 357 dyno numbers..

Graph? Where did that cam peak?

Is this a custom grind? How does the cam drive? What springs are you running? Lifters?

Sorry for all the questions, but I'm interested in this cam for my 396.

Yes but they sent me the wrong crank it was supposed to be a 3.48... It was supposed to be a 355. But i'm not complaining, lol.

I will get a graph up in awhile.

Yes it is a custom grind. It drives like crap! Springs are isky(forgot what number). Lifters are the old style comp Rs.(The good ones).
