MS4 + Heads or Fast 90/90 ??? I'm planning on building a 408 with a blower in a year or two but in the mean time I'm wanting some extra power and an aggressive cam. I'm trying to decide if I want to get the TSP MS4 cam with a FAST 90/90 combo or if I want to go with a pair of their Stage I LS6 heads. I'm kinda leaning tword the FAST combo because I'll have to purchase new heads when building the 408....Plus I can use the FAST intake on the new motor. At the moment I can only afford to get one or the other....What would you choose?
BTW, I will be using a totally different cam for the 408 so that it meets the needs of a FI motor.

Depending on how soon you were gona build the motor, I would just get the cam. If you decide to go with L92 heads, the Fast intake wont be any good to you.

Hmm, never thought of using the L92 heads/block. But with having FI, I wouldn't think that a few more flow numbers over the Stage 3 LS6 heads would make that much difference. Maybe a few HP but when your at the 750+ RWHP range traction isn't on your side anyway....
