What to do with my 360

How fast do you want it to go or how much HP? Figure that out first then start accumulating parts.

A true 350hp will get most a-body cars in the 105mph range in the 1/4 which could run deep in the 12's with a good chassis/converter. 350hp is not hard to get out of a 360 with a mild hyd camshaft.

Simple piston is a KB107, no need for a forged crank in a 360.
