331/347 stroker kit/components

[347 Stroker]

Well, It's about time to get my block machined. I still haven't decided on a 331 or 347, I'll probably lean towards the 331 due to longer life. I would like to get the components rather than the complete kit at this time, just due to the lump cost up front. I realize that I'll spend a little more this way, but at my current state, I'll have to go this route. I need .040 over pistons, just due to some standing water that got in the block before I had it. .030 pistons would work, but I'm more comfortable with the .040. All the kits I've seen have either .030 or .060 pistons. Who sells .040 pistons? What is a really good brand to go with, as far as pistons, crank and rods? I'll end up buying the rotating assembly from the same co., but not as a whole kit. Will all stroker cranks, both 331 and 347, have to be balanced? I keep reading that most, if not all, are for a 28 oz. dampner. Any websites or other info is greatly appreciated. Thanks in advance!
