Port size matched to cam specs.
Im trying to match my cam specs to the intake port size for a 388 with 10:1 compression
cam specs are:
Duration @ .050" lift:---> 240/246
Valve Lift: ---------------> .507/.510
Lobe-Center Angle:-----> 110
RPM Range: -------------> 2300-6500
I was thinking along the lines of 200cc intake port, aluminum heads with 64cc combustion chambers. This is going to be a strip/street car, Basically i want the most bang for my buck even if it means giving up road manners.
Thanks everyone!

Re: Port size matched to cam specs.
195-200 would be OK, but you could easily go bigger... that engine would probably really like a 215cc or 220cc head.

Re: Port size matched to cam specs.
I think an AFR 195 or a Dart Pro1 Platinum 200 would be the better bang for the buck, but since you're chasing peak HP, you'd get more with AFR 210 or Dart Pro1 Platinum 215s
