Like Tech says, why not bigger? Since a 302, 350, 383, 400, 265, 283, 262, etc all look pretty much the same outside AND building a motor costs about the same regardless of size, build the biggest and call it a 302. Besides, nobody but you gives a darn how big or little the motor is unless someone is doing a tech inspection for a class with rules. Sure, a 302 might rev higher with the 3 inch stroke, but revs don't get you to the finish line first or lift the wheels higher.
