Comp Cams Xtreme Energy 268 ?s

My engine builder has offered me the above mentioned cam (& matching bore lifters) that was removed from a '65 Cuda with a 273. He told me the cam wouldn't allow the Cuda's power brakes to work properly, so it was removed after about 200 miles.

My 120,000 mile engine is getting a basic stock rebuild with a .030 overbore. It does/will have an Edelbrock LD4B intake & 1406 carburetor, double roller timing chain/gears, MP electronic ignition, factory exhaust manifolds with FlowMaster 40s and 2 1/4" pipes, factory heads (with hardened valve seats), A904 transmission (stock convertor), and the factory 3.23:1 sure-grip 8 3/4" rear-end, with P245-60R15 tires.

I'm "camshaft dumb", so I'm looking to the FABO experts for guidance. Is this cam to much for my ice cream parlor cruiser? I love the sound of a lumpy cam, but I don't want to lose the reliability/drivability of a stock motor. I also don't want to have to "need" headers or a higher stall torque convertor, etc...

What do you say?
What cam number are we talking about there? Comp has numerous High Energy and Extreme Energy cams that fit in the "268" arena. Apples to oranges. There are a ton of 318 cam threads here on FABO. The consensus is to call a cam company with tour combination specs and they can recommend a cam or grind you one.
