[QUOTE="PNWSVT, post: 16054154, member: 192698"] I ended up making a ton of piston stops, so ill be selling those lol. Thank you old plugs! As far as the wobbly crank socket, i inserted a piece of brass that fit the I.D. of the socket, and left a cut for the keyway and it worked way better, I probably took 4 degrees of play away from the wheel. But theres still 2 or so degrees of play. I figured out what needed to happen with checking the centerline of the cams. It took multiple trials and errors and bottle of black velvet, but i got it down. I wound up with some numbers i wasnt expecting This is all drivers side or left bank results Intake 120 degrees. (I did this test about 20 times, and then once I tried it again and the degree wheel spun a few degrees off, it didn't matter because I just found my max lift, .50 before and .50 after and the numbers were still the same) Exhaust 114 degrees. So the numbers seemed a little off from where my comp card said. As well as I was being told that Comp cams are 4 degrees advanced from the factory? cam card [URL]http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=964&sb=0[/URL] using that Mark Olson cam calc with cam specs off the card [ATTACH=full]1528437[/ATTACH] Now with my actual results [ATTACH=full]1528438[/ATTACH] Thoughts?
