I already checked out an article on here: Total timing. But too much arguing back and forth about timing set up? Here's what i am dealing with/ engine set up: 85 318 engine block with flat top pistons not high compression but only 9.1 compression . Short block was built by a really good machine shop and cam was degried correctly . Rest of short block is stock . Here are the cam specs: Erson cam part number
E 420121 GRIND: TQ20H
Lobe separation angle 112+4
Overlap : either 68 or 88 ?...
Performance timing
