1st 340 build

I am on a very limited budget and am really trying to avoid machine costs.

Then Superbee's idea isn't very practical. My advice would be to find someone who is building a stroker and buy their stock bottom end. Earlier cranks are forged and internally balanced, later cranks are cast and require a special harmonic balancer and weighted converter. Both cranks are fine for a street car, but would need to be checked out by a machine shop before installing.
