I am not well versed in all that you guys are trying to achieve, but I thought I'd point to Tom Langdon's Cadillac 261 article in the Sept./Oct.2003 issue of 12PN. After boring and using an offset crankshaft with Cadillac pistons and 292 rods it's possible to reach 290 cu.in. out of the original 261. The pistons were from Cadillac 368 cu in V8, 1980-84, with a std. bore of 3.80" and then the appropriate overbore to get the final cu.in. one would want. Without head or block milling the piston below deck is .046". All these parts would be easily found at any parts store and cheaper then special made pistons or rods.I don't know if this helps, but I thought I'd point it out. In any case I am enjoying your discussion.
