I'm glad you did the research. I can't tell you how many times I've told guys not to build big RPM Chrysler stuff without a new block with correct oil timing or fixing the oil timing the way I did it.
In fact, I refused to build them. I tore enough **** up myself making me look stupid learning how to do it that I didn't need customers helping me.
This is also how I know many (if not most) of the guys claiming they were turning big RPM's and making power were either full of ****, had a bad tach, or were just smarter than me. Most likely the last one is correct.
Interesting stuff. I hope everybody reads these threads even if they never build high a RPM engine. It's good to know that those who came before us, who didn't have computers, weren't as stupid as we thought. They had it sciences out.
I also think the guys building stuff at the time they engineered this crap never thought anyone could make power at RPM ranges where oil timing would be an issue.
