Proposed 400 bb build, cam recommendations

So your looking to make 600hp with a 200 shot? not NA.....if I remember correct IQ52 made 440-ish hp with a 7.85:1 400 with iron heads that flowed [email protected], an 850DP and the mopar .509 hyd. and stock rockers that weren't 1.5 ratio so lift was under .500 and with a single plane/hdrs.

I wouldn't use a hyd. cam but as suggested the mopar .528 sft with your 3500 stall, don't know what your vehicle weight is (3300lbs?) but at 600hp, 3.91's and 28" tyres you'll be crossing at 6120+slip if it hooks using the N20 on the hit and 6800 in the traps at 10% slip? just for reference.

And for other info, my mates 3150lb Dart with a 440 at 12.5:1, Ported 315cfm Eddy heads, victor intake, 1050 Dominator, DC.590"sft made an on track 600fwhp NA, 10.12@132 and 1.38 60's, was shifted at 6300, trapped at 6800, 4.56/31" tyre.
