Here are the specs on the motor, just looking for input and maybe other peoples experiences. I really just want to know how much the ls6 intake is going to hurt my numbers! This motor was built for nitrous, the car is already set up for a wet shot from the previous motor.

Compression is right at 12.8:1-13:1

Let me know what you think...thanks

Its very possible but change the 1.3/4 headers also since why the small cam for the setup??

What fuel areyou planning to run??

Good luck man but a ported 92mm Fast Intake and 92mm TB Will really wake the car up.

This will most likely be a race gas motor as the compression is too high for 91 but ill leave that up to the tuner...i feel like that is a decent size cam....just wondering how much the fast will "wake the car up" as opposed to an ls6

thanks

You could get the LS6 modified to 90mm by TPIS cheaper than FAST and almost same returns.
You'll need a 90mm TB

Your cam is a bit small for your power goals, I would gather all the parts and get a cam custom speced for your application.
