keep in mind, the cam in the 360 was going to have a stock torque converter and highway gears... started as 2.45's and now 3.23's. Better converter and gears, the engine would come to life with a better cam. It's why I say, if you do not plan to go to the drag way or race the car ever, just want low end torque, I think a factory 318 cam can deliver what you are hoping for. I would focus more on the tune of the ignition, quality timing set, a good valve job, etc
