Default I want to hit 400rwhp. Help!

Hey guys, currently i'm at 377rwhp with mods in my sig. It's basically a cam-only hawk with a bunch of bolt-ons. I've recently got the mod bug again i'd like to shoot for the 400 mark. Without doing any big mods like heads or forced induction (at least for the time being ) what could I do that I haven't already done that will put my at that mark? I was thinking underdrive pulley, alternator pulley, ported TB? Any other ideas?

Thanks!

Should be extremely close with the pullies and throttle body and more aggressive tuning. That cam is similiar to mine, so I hope mine performs as good but I'm going heads and cam route!!!

Fast intake, underdrive crank pulley should get you there. IMO the FAST is only gonna make the big gains in the upper RPMS so those mods are gonna be quite a bit of money for a RWHP number without a ton of SOTP power.

i wouldnt spend the money on a fast intake until I got better heads waist of money IMO the ls6 intake has been proven to be a great intake I would port it before going with a fast 102 and I wouldnt go that big of a intake on stock heads not much point.

you can probably hir right at 400hp with a underdrive pully and a ported or aftermarket TB.

but you really need to look into just getting a set of ls6 cnc ported heads it would go NICELY with your cam and probably give you some really nice gains and get you well over the 400hp mark all for 1100 bucks, and a head swap is easy

yeah professional products makes it. there is a writeup on how to do this. combine this with a 85mm MAF/smooth bellow, ud pulley, and a new tune. he really should be at 400.
