Rebuilding wd motor

You have to change to dished top pistons (Power Crater). Sometimes we had to grind off some of the inside block so the crankshaft could rotate. To complete the upgrade required changing the carburetor, air cleaner and possibly the manifold.
 
I doubt very much that you should use old sleeves with new pistons because the ring groove in the old sleeves will destroy the new pistons/rings. You are looking at a new set of pistons/sleeves for a WD-45 or D-17 (either will work) and a WD-45 crankshaft. No block grinding required.
 
NEW SHIM STACKS FOR THE MAIN BEARING CAPS !!! AND PROBABLY FOR THE ROD CAPS IF THEY HAVE THEM, IF THEY ARE WD RODS. WD45 RODS WERE NOT SHIMMED.
 
Thanks for info
I was going to boil the block with sleeves in
I don't know if there are o-rings in between block and sleeves if so does boiling mess them up
 
There are Orings on the sleeves. Do not boil it out with sleeves in the block. Did you read where I said you cannot use old sleeves and install a WD45 crank????????????????
