Hi all, my names josh. From Aus amd have a 408 smallblock (stroked 360) in my valiant. Running a 6pack setup on top. Approx engine specs 11.1 comp, alloy heads, solid cam 244/252@50, 520/540lift, 5spd manual.
Just recently had on dyno to tune carbies, had 66 jets in center carb and approx .89 in end carbs. On the dyno pulls (chassis dyno) only made 340rwhp. Still stout but made pwr only to 4600rpm then nothing really after. Obviously heads need some port work and port matching the intake but curious as to what rpm and pwr the 6pack intake is good for? Wanted to bump up my cam to another solid flat tappet, lunati 582 lift, 255/255@50 108deg lobe. Would this be too big or ideal for 408ci with 6pack. Thanks josh
