.060 milled off i came up with about 9 or 10 cc's, i can't remember the formula exactly. i think its for every .06 milled =1 cc off the chamber. so .060 would be 10 cc's or so, all i know is it should help the comp. a bunch lol.,
also stroker i read your frankenteen buildup, nice project btw.. if your running the lunati 60403 with 1.6's and no problems, then i shouldn't have any clearance issues with my xe268 setup, i will check it to be sure, but i highly doubt it.
