What Richard was trying to help you with is to get the proper pistons because the generics have a bad tendency to stay deeper in the hole than prefered. If the pistons are down in the hole deeper than is acceptable, the squish will not be enough for effective compression and flame travel. therefore the block should be milled. Get the right pistons and you won't have to go through all that.

What excactly does the machine shop do when they internally balance it? Do they do this after the rotating assembly is in place?

Part of the balancing process is to ensure that all rods and pistons are exactly the same weight. That is done prior to assembly.

Thanks, does the 305 crank give it a shorter stroke?
And would I assemble the rotating assembly before taking it to the shop? or do they balance it out of the block?

Oh, nevermind. Thanks
