273 commando cam

I am building a 66 273/235 motor for my 65 Barracuda and talked with the tech rep at Racer Brown. Discussed in depth the specs of the motor (basically a stock 10.5 motor 4 barrel, stock exhaust manifolds, stock exhaust with muffler and resonator, transmission (4 speed), rear end gears (3.23 SG). Bought a custom ground cam per his recommendation. Bottom line - talk to your cam company and give them as much info as you can.
