[QUOTE="olympic, post: 16280301, member: 168598"] I have adjustable primaries and I ground the keys right off my secondary gears when I degreed them. Todd Warren (the mod motor cam guru) has a guide posted on his facebook group that says to do it this way. (or grind all the keys off if you don't have adjustable primaries.) Install ARP bolts in the cams and torque them to 125 lb/ft. Are you sure there isn't a couple typos in there? I think the intake valve open spec should read "-3* BTDC" or "3* ATDC". The exhaust valve close spec should be "-6* ATDC" or "6* BTDC" See chart below. Here's a handy chart to help visualize what's happening. [URL="https://www.classictiger.com/mustang/CamChart/CamChartCandDr3-1.htm"]CamChart[/URL] Plugging in the numbers for your cams and it looks like this: [ATTACH=full]1596566[/ATTACH] According to the specs on your cam card listed in post #5, the exhaust centerline is definitely 118. Installing all 4 cams at 114* centerlines will still work. Our engines are not very sensetive to exhaust cam timing. Intake timing has a greater effect. I just installed a set of Crower Stage 2's which are very similar to yours (222/222 duration,.475/.475 lift) and degreed then to Crowers specs which were 110* ICL, 118* ECL, 114 LSA.
