Stroker small blocks - what intake?
What heads are on it? Those numbers tell me it's got too small a port (my opinion anyway...). The port includes the intake's passages, and the plenum size may also be a little small. That HVH (if it's the 4 holer)the reduces plenum size, usually adding torque and lowering the rpm the peak is at, on an intake that may have a small port, but a larger plenum. (It helps bend the air, and reduces the large single plane plenum.) Does the torque drop off, or stay strong until near the HP peak? What is the cam's lift and rocker ratio?
