So after I blew my motor up in Phoenix, I bought a motor from a friend, and used the short block with cam installed, and replaced heads, etc. with my parts. Didn't tear down the short block to inspect it, did a quick check on the cam and found the intake centerline to be 108, which is, in my experience a pretty normal number to see for a big block Mopar. Went to Great Bend for Div. 5 event, during T-N-T found that the car was just a TURD! I withdrew from the event and brought the car back home.

I researched the cam specs online, and an intake centerline number is not given, just opening and closing numbers @ .050. When checking those numbers it appears that my cam is 12 degrees retarded, meaning that the center point of the very top of my intake lobe will be at 96 degrees. That seems crazy, I've never run a cam with the intake centerline that far advanced. Any thoughts??
