        you have to have the proper clearance between the piston and the cylinder wall, these clearances are piston specific.
        The machine shop that i used obtained pistons for me. Speed-Pro #SIL3409+20.
        the rings are Hastings HAS2M4649+20.

        If possible, the machine shop should want to check the block first to determine the amount of over bore it will take to "true up" the cylinders. Then, obtain the replacement pistons, measure each one, and bore each cylinder to match a piston, this way you get the best fit for each cylinder.

          Running stock pistons with oversized rings is not gonna work out too well. You should definetly have the block checked out and have it bored to what is needed first. If you get the .020" over parts now and the shop has to go larger, it will be a waste.

          Only news on the TB is that the plates weren't done, they were only 65mm, not 69. Im still looking.
