Depends on what you want to end up with. If the goal is a 302 car then rebuilding the 200 is money thrown away. If you still need a 302 you may have to get that rebuilt anyway, unless you know the car it came out of. I guess the answer is the 200 would be cheaper if you would be keeping it that way.
It just dont have any pickup and go I was following my dad in his 69 ford custom and he leave my in the dust and it only has a 240
