I apologize if this subject has been covered many times before.
I searched the tech archives and did not find the answer to my questions.

Currently, I have a very high compression, (205-210lbs cranking on the starter) 3.51 stroke 340, that requires at least 50% race fuel. It has become less than pratical, especially if I want to drive it anwhere beyond a 1/2 tank. This is a street toy.

I have a disassembled, standard bore 360 that is begging me to do something with it. Of course, I don't want to sacrifice power, so I have been thinking about the 4 inch stroker crank.

I have a nice set of J heads, and will probably stick with them.

Can someone give me some advice on pistons and build for this 360? I have never messed with an externally balanced motor before.

Thanks in advance for your help! If there is a link to where this has been covered, I would appreciate that as well.
