Mars_302, I would get ahold of WynneSpeed and see if the can ship you the balancer and flywheel that they used to balance the assembly. It's strange they didn't send it with the long block.

FordMan, the NASCAR take-out motor isn't a bad idea if you are going to use Yates heads. If not, you might be looking at changing pistons. Depends if they are going to be compatable with the heads you chose to go with. Why not just put it together yourself? Then you know everything was done right. Talk to Strokd85. We just went through his motor a month ago in his garage at home. Nothing to it.
