People with 30# inj's pass easily, and 21#'ers make well over 200 RWHP
so 30's should surpass 300 RWHP. 36's at least... but anyway, the bigger
inj's just turn down the pulse width at idle as compared to the 21's.
If one of my new cams in a 4.2 is ever properly tuned and installed, we
may already be at 300 RWHP but I have never heard if he did it. He was
also needing better intake porting to match the heads/cam combo.
A 3.8 going over 300 RWHP would need short runner intakes to do it NA.
