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?
