Oh...got it. I don’t think that either. That’s why I asked if he verified TDC. Most boxes retard 4-6 degrees and start a little above max advance and then changes with RPM.
Not that it matters but the engine was built and raced for two years before I bought it. All I did was install the trickflow heads. Well i did install a new PRW harmonic Dampner. But i hope it wouldn't be that far off. But you never know.
