Estimated HP with these mods

[JayErnie]

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)

Your going to need to buy more part than that but if your talking just straight numbers id say we cant tell unless you tell us what heads and CAM. But def 420+rwhp if its done right.

[sfletch2000]

if your looking for 400 rwhp theres no need to even change out the heads. Bolt ons and a cam will get you there.

Any other Bolt-Ons should i put on?

For the heads, it'd be hand porting, not CNC, i guess equivalent to stage 2 porting. Can't tell you for the cam since I know nuts about them and for the rest of the setup, I don't plan doing anything on the intern parts of the block until winter.

So it'd be all bolt-ons with a cam and heads.

By the way, 78mm or 90mm TB ?
