Sudden Power Loss (opinions)

Compression test will hide the issue I had! Punched Exhaust Rocker and missing intake pushrod on #1. Had full compression on all cylinders. Just this year!

If you have ever been to a NASCAR race and a car had a Valve train issue it sounds like something is trying to blow out ,but flat and can only push by the rings! This is what my 383 sounded like afterwards.

Use you laser Temp gun to verify. I have stock Cast iron exhaust! Point the laser near the head at exhaust exit!

#1 for me was 75 Degrees! The rest about 450 to 480!
