I am building a WC with a gleaner block. Going to a 6 inch stroke and possibly a 4.5 or 4.25 bore. I can't decide between the piston size. I am going to be pulling NATPA 2T. I already have a head with 2.125 intake and 1.625 exhaust. Carb and Manifold have been worked on too. Would I have enough power with the 4.25 bore??

At least 4.5

If you go bigger than 4.3 the stock head gasket won`t work, for top cut
3 mph the 4.25 will be plenty of power,your valve size, the exhaust side
is really not that bad, the intake side, it will take a lot of work to get that big of valve to work.
