Hey Johnny I got another call back from Comp Cams. Seems they misunderstood me over the phone. They now say the cam is a solid flat tappet pn 11-601-5 grind # CB 259A-8 (sound familiar). This bad boy has .629 Int. .605 Ex. gross valve lift duration is 260 and 266 @.05. killer drag cam. Cost is $228. bucks. Not bad for a $25 dollar swap meet find. Thanks again for putting me on the right track.
