I'm not quite sure. A friend of mine owns B&R racing, which a mustang speed shop here in oklahoma city and i just bolted the heads up and took him the cams and the timing components and he degreed them for me. I can check with him and see what exactly the specs were if you're interested duffman.
The 315's give our cars such a muscular look...lol, I just had a chevy guy say he usually hated Mustangs but he really really liked my car!! The stance & tires etc...won him over!
