Maybe you have some bad compression going on in one or more cylinders. Rings may be damaged etc. Do a compression test on all 8 to see what's going on.
My buddy had a Ford 400 c.i. that was doing that and we comp tested it and he had crappy compression in one of the cylinders - threw the whole engine off and it shook all the time, as if it had a misfire.

Did a compression test and its good,starting to think its a fuel issue,all plugs look the same,flaky white....havent got a chance to work on it yet but will let you guys know.Oh and yea...no tfi stuff here.

Alright new plug wires on the way,I pry should have started there first but could a rocker being too tight do this?They are pedestal mounts though,also on a cold start it doesnt seem as bad but its still there....well see what the plug wires do.
