Engine and Bottom End / 87 stroker motor build help

« on: December 06, 2014, 12:39:29 PM »

when we put it together, it broke up top end badly no matter what jetting we ran. dumped a half can of Klotz octane booster in it and runs mint. but would like to drop compression a bit so it will stay together a little longer. im guessing the high compression is the culprit for chewing the pin bearing within 20 to 25 hrs

We are trying to get compression down on an 87 stroker build and wondering if anyone knows of thick head gasket that i can order? Compression is at 205 at the moment and we dont want to run race fuel. We have had the head machined to hotrods specs and still too high.

I have a esr310pv motor stock stroke crank (88) curtis sparks pipe, boyesen rad valve and a 38ml carb. I have read countless posts saying that people are running 175-18? Main jet, i am at 300ft above sea level and i cant get mine to run any bigger then a 158 main. Any bigger and it crackles top end and fouls plugs, the plug is perfect in colour and have done countless plug drops. Is this a problem?
