Default 90mm intake question

I have a MS3 cam, prc stage 2.5 heads, LT 3'' duels, bullets, 85mm maf, LME 5.7L
3500 stall.
if I put a 90mm tb and intake would this help or hurt performance?
what brand should I go with also?
thanks

The FAST LSX90 would help quite a lot, especially if it's port matched to the heads. 20-25rwhp wouldn't be unreasonable.

Nick Williams 90mm Throttle-Body is the only way to go.

The injector thing varies for everyone, I've heard of people running 100% duty cycle with 410rwhp yet I'm not maxed out (though I'm close) with the smaller 99 injectors and 455rwhp. If you can afford it though, I'd recommend you step up to some bigger injectors now.

By the way, get a FAST, I like mine.

Well it really depends on your future mods. It's not good to run too big of an injector even if you tune it right, as it wont spray as efficiently. I believe my new setup is going with 32-36lbs, although I'm waiting on Allan to hear for sure.
