what horse power are you runnin with those mods? have you considered a crane cam swap?
in a mustang and fast fords mag they did the swap and showed 347 at 4,200 rpms, only other mod they did was the accufab tb/plenum, they put a 75mm on there

RE: cam swap...throttle body?
This will be open to debate but I got an Accufab 75mm for my 04 and the larger size didn't hurt at all.I will venture a guess and say that the extra airflow from the P+P job could make very good use of the higher airflow.Port velocity is important but since it begins in the intake manifold I don't see where the lower velocity from a bigger TB would hurt a fuel injected car.MMFF did a test with their test mule engine and the stock crank HP was 390@5900, the 70mm TB produced 399hp@5800-6000,and the 75mm made 407hp@6100 rpm.

Full exaust with LTs, full intake boltons, u/d pullys, a tune, and a set of good cams should make about 290 RWHP on a 4.6 SOHC GT.

I dunno if this is what you are sayin, but I hope you don't think your gonna be making 347 horse out of a stock 4.6 with just cams and a t/b, at the wheels or the fly.
