I have a set of Probe BBC pistons, 4.280 bore, standard 6.135" rod with 4" crank. 18cc dome, would make about 9 1/2 to 1 compression depending on deck height, head gasket and cylinder heads used. The one on the bottom left shows that it hit a valve, believe it would work fine on a budget build, simply have a shop pin fit that one piston. $100, located in Parker, if shipping is needed, that would be on you.
