Is it feasable to bore / sleeve a stock JD late A block for 6.125 pistons? Would a stepped sleeve about .25" wall work (step at top to hold it in block)?

Thanks,

I'm in the same situation you are in only with a mid A. I have a stock block needing sleeves and a Power Block also needing sleeves. I would rather put big sleeves in the stock block, for rule issues, than in the power block. How big will live and who to have do the work to make it live?

As Ironman stated, there are A blocks running 6.750" bore. If all you want is 6.125", you could pay $1000 for a 6-3 and come out money ahead and unless someone let it sit in a hot tank, you know it will hold water when its all said and done.

If you sleeve your stock block, I wouldnt stop anywhere near 6.125, because it doesnt cost that much more to go BIG! And make d@mn sure that the sleeves are fastend in so they cant come out the back instead being pressed in and smeared w/ windshield goo and praying they dont come out. I know of several press job w/ windshield goo blocks that became hand grenades. BUYER BEWARE!!

I am sure a powerblock would be the most simple, however, no JD part number on it. If I bore and sleeve my own block at least I will know what I have. Any idea of a sleeve for a 6.125 or 6.75 bore with a flanged end?

I think they can bore and sleeve JD A blocks out to around 6.75", so it's definitely possible. 6.125" should be reliable, but there are many out there running bigger than that.
