roller cam chain conversion

[entropy]

The only way the stock chain try's to climb the sprocket is because the tensioner is set to loose or it also trys to climb when turning backwards..Trust me if there is no play at all the chain does not try to climb especially just degreeing the cams.

yup, i don't do that no mo'

My exhaust cam timing was advanced when skipped. Lost about 18hp when that happened. I had .445/.415 cams and 65lbs springs.

Yikes, so the valvetrain inertia skipped it! Same as turning the crank backwards, wow I couldn't imagine that happening.
The intake stayed in time with and advanced with the exhaust?

lucky it was the exhaust cam rotating forward and not
the intake cam,they idle like a top fueller when the exhaust cam is
1 tooth forward.

Only the exhaust cam. I didn`t notice it right away when it happened, i was doing some amateur drag racing and there came one "pro" to look at my time sheet, he said "you should check your cam timing", how did he know

Did it break the upper guide when this happened?

If the crank is turned backwards the int advances (more lift) and the ex is retarded (less lift) at tdc

Yes, but it stayed in place with the other bolt. I guess i kept timing chain too loose, but it was quite tight before and it started to stretch, hard to find right tightness in the middle.
