Re: Opinions/Guesses on new combo
I think the RPM intake might limit it a little, but what do I know? I'm take a WAG and say 470hp at 6300rpm and 440ft/lb at 4500rpm... but who knows I'm probably waaaay off lol.

Re: Opinions/Guesses on new combo
470 sounds right..... 6300 RPM's sounds right... maybe a bit more torque, 500 ish....

In a 3300 pound car, easy 10 seconds....
