Hopeing someone out there has come accross this and can help shed some light. I have a animal big bore stroker with billet head that since the start of this season cannot get to run right. It makes power like crazy and has tons of torque but once it nears 3/4 throttle falls on its face and stutters like its jetting is off or there is something wrong with timing. I have tried 3 different carbs, with jetting and even switched from methanol to gas. I have had 3 different coils on it and tried different gaps as well as different flywheel with no luck. Cam timing is correct i checked 3 times. Has great compression. New roller rockers, new valve springs, checked push rods they r straight. We have been building our own motors for years and have never been able to not diagnose something but this one has me and everyone else i know stumped. So im reaching out to the internet looking for any ideas or direction what i should try or look for next. Thanks guys
