F.A.S.T. Intake or carb setup !!!
 

I've been hearing that the carb setup for the ls1 is making more power than the fast intake and nw throttle botty ? Is this true ? And its not like 30 or 40 hp either its like 100 to 150 hp gains (for my setup) by switching to the carb setup if ne body knows about this post up !! I am thinking about switching over :drive:

100+ RWHP from an intake? Not likely. Even on your 408 I would guess no more than 15 if that. The cam will be way off for the carb style.

I would go with the 90/90 setup. The carb setup is nice but 100rwhp claims = :turd:

100-150 hp gain with an intake???.....not without a direct port kit attached to it. :judge:

if it was even remotely close to 100hp gain everyone would have a carb style.
reading your sig, the 90/90 would work best for what you are doing.

I think my carb intake is worth 50-60rwhp
