Dave and shawnlee28, have read many of your responses on this forum and found them very informative. I understand what you're saying but I don't think you answered my question. Probably just me, but anyway....

I already have a 2 piece seal crank along with rods and pistons but I can't seem to find a useable 350 2 piece seal block for a fair price in my area (I had a block before I bought the crank but the block turned out to be unuseable so I need another). However, I can find 1 piece seal blocks. So I guess I want to know if the adapter and tool I mentioned, is all I need in order to use my 2 piece crank in the newer 1 piece blocks.
