360 pros & cons vs 318

Sorry forgot to mention the cam in my first post. Tire size is 245/60/14. Spring relocation done, and tubbing in progress. Has coilovers on the rear, and thinking of what i should get for the front?? Has new disk brakes as well( up front) drums on the rear. So i dont know what exactly i would have to upgrade for a big block? Torsion bars good for a big block or would i need bigger ones? Sorry i couldnt tell you the stall if my life depended on it. It burns rubber for a very far stretch of the block. Just doesnt scare the crap out of me like a hot big block car.
