Rebuilding a 40 over 350 speed pro hypereutectic w/coated skirt 3.5 dome, dart iron eagle platnum heads 230 intake runners 2.08"int/1.60exh, comp cams extreme energy with 520/540 lift and 282/290 duration with solid lifters. Witch rockers should be used 1.5 or 1.6 rollers, thinking 1.6 would be bettet. How much horse power do you think it will make with a performer intake and weber 750 carb? Its going in an 81 elcamino 4sp.

 

well those heads are alittle big for that combo, but we will look past that.

The intake does not match up with that. You need atleast a rpm air-gap, if not a victor jr or Weiand Team-G to complement those heads.

If you havent bought the rockers yet, put 1.6s on the intake, and 1.5s on the exhaust.

also what is the LSA of the cam?
