I haven't checked the cranking compression.The rear tire is a 275/60/R15.The trans is an older 18 spline which I believe has the original 1st gear in it. I'm guilty of tuning it like my automatics.The post has opened up my mind a little more. I just have to do the homework.
A 275/60/15 is a tall tire,try a 295/50/15 it will be a bit shorter and help gearing but you may need wider wheels. I agree on checking cranking compression and either advancing the cam if possible or a milder stick as suggested.
