Fast 102 or Ls6?
Guys Ill be finishing up my head and cam swap along with a few other things. Ill be around 430 to 450 hp. I cannot decide on which intake manifold to purchase. I was initially going to get a Fast 102, but if I do I'de also have to get new fuel rails, and a new plate kit for my nitrous. How much horsepower will be lost if I decide to go with an ls6? I have the Prc ls6 2.5 heads and a 228/230 .588/.592 112 LSA. cam shaft in it right now. I'm beginning the final steps to get the valvetrain back in order then its up to the intake manifold. Any thoughts?

I agree, I'd just focus on making the ls6 + what you have the best it can be, everything ported and polish, etc. My combo is the same as yours roughly, and there is no way I will do a fast intake unless it's about the same cost as a ls6 if I see one used.

the FAST 102 is superior to the LS6 intake (except under 1000 rpm, but who cares) and to the previous 90 and 92 versions to. the 90/92 FAST intakes tend to make great power in HP and TQ, while the FAST 102 you could probably squeeze a few more torque out of it with the same setup and definitely more power.
