so please clarify what you have with some part numbers and pics

It is defiantly a 2P style crank, I cant use a ext balanced flexplate because the weights are in the way of the spacers that attach it to a IHC converter, It uses a stock Chevy flex plate that has been redrilled for the IHC converter, there are 4 spacers that make up the thickness of the adapter plate between the motor and the trans, there is also a spacer that fits in the back of the crank to center the converter. I wish I could use a 1P seal block, the internal motor already leaks enough oil, I wish I could do a full Chevy motor/trans swap but then I would have to make new drive shafts, trans mounts and a lot of other things and I am not sure the if the transfer case is on the same side as my Scout. I will try to get some pictures up as soon as I can.

That looks like a pretty good deal, I would like to go with a Hyd roller cam.

I am looking at rods for this build, I am going to use 5.7's with a bushed pin and some thing that I don't have to bushwhack the block too much so they don't hit. I had thought about having a set of stock rods rebuilt and bushed but I can probably get new ones for not much more. Next, Pistons
