Can anyone tell me what the lifter bore angle is off the blocks vertical centerline? I did some rough measuring and just want to check my findings.

I think it's called out in the drawings in the Power Source book. Does it look like it's not 45? I ASSumed it matched the bore centerline angle.
No, the book doesn't show it. It is different than the cylinder angles. It's either 41 or 42 degrees.
