Estimated HP with these mods

Hey guys,

Time to put up some juice in. What would be an honest gain of HP with these mods on a 98 Formula M6 tranny:

-Volant Intake Dual Cone Air Filters

-90mm Fast TBI (I removed the grill into the MAF aswell)

-Fast Intake

-Ported Heads

-Cam (To be honest, I duno what kind of lift, go with 80% performance)

-Longtubes Headers (Prolly Mac ones)

-Catback (Prolly SLP loudmouth or Magnaflow)

With that set up you should be close to 450-500hp. Thats what I've seen that set up do in a magazine.

I thought Mac only makes mid-length headers for f-bodies. Which cam/heads you choose will greatly impact the performance.

mac doesnt make long tubes, and knowing the cam specs will help a lot along with the type of heads

However the right h/c combo and supoprting mods could see 450-480rwhp depending on the Dyno used.

500rwhp from a 346ci LS1 n/a and setup for street use is total bollox and not going to happen.
