Dave, if I recall correctly, you purchased those pistons for a little bit of nothing, if you had some spare parts floating around, have access to relatively inexpensive machine work, and a desire to do it just for grins, it would be kinda cool to see how it would work out.
There was another thread about a year or so ago where one of the members mentioned using 6" Chevy rods, and .060" over 283 pistons after turning down the crank to match the block and the rods, and it would put the pistons like .005" in the hole. He also said the parts are "...as cheap as dog food" which wasn't much of an exaggeration. I found a set of 6" used SCAT rods for $125 (3/8" ARP cap screws) and several different types of pistons for good prices.
It was an interesting prospect.
