For example: 268 high energy #CRS268-H10 218/218 268/268 .454/.454 110°
268 Extreme energy # CL20-223-3 224/230 268/280 .477/.480 110°

Yes Mike, I saw the multiple 268 choices. The only info I got from my builder, is "Comp Cams X-treme Energy 268 Hydraulic". It's not enough information for me (I'm cam "dumb") to say yes to using it. From all the info posted here, I'd have to make other upgrades/changes (headers, torque convertor, etc...) to the car to make that cam work. I'm just looking for a simple/stock/reliable rebuild of the 318.
