Ok, I built my current set up not too long ago, had it dyno'd and wasnt too happy with the numbers, I'm looking for more power. My current 2v put down 275rwhp and 267rwtq which at the track has a current best of 13.1@107mph w/ a 2.1 60ft, which tells me with a better launch is good enough for mid 12s.

Here's the thing, I'm tearing this motor out and have the option of getting a 5.4 short block for 350$. I was considering building that and putting a lightning blower on it w/ my current PI heads. Other option is I have some 4v 93 lincoln mark 8 heads laying around that I could use on the 5.4 then spray it, but to my knowledge I wouldn't have a intake to match. Or keep the 4.6 and build it for forced induction???

Im torn in too many different directions, I really need some help in deciding what to do.

Throw some nitrous on what you have right now and see where that gets you if you havn't tore the motor out already.

Couldnt you use a navigator intake manifold on those mach 8 heads on the 5.4? The navigator is a 5.4 DOHC
