Mike I agree he has a pretty efficient combo, but even pro stock engines have about a 1500 rpm split. Just seems odd to me. It may be valve springs or pushrods making it so peaky I don't know for sure. Just a stab from what I've seen with engines I have dynoed. I could be wrong ?????

I agree with this, shorter stroke engines should still carry a wide torque curve.

Glenn's engine still has a longer stroke as compared to NHRA super stock engines running higher RPMs.

I believe Glenn has had multiple issues with rocker arms, maybe sending the stuff directly to Jesel may be able to provide insight.
