I don't know of any other pistons that will fit the 194 either, though. 283 slugs will work in a 230, 307's in a 250. Not enough wall to bore it over 3/10" to make a 230. Might as well find a bigger engine, like a 292? Or a 250. Keep the 194 head, more squeeze.

well good for you the POPE... CH of the 194 is about 1.792 so a .283 is 1.800 but bore is to big the only forged piston that small of a bore and could work? is v6 buick and the ch is around 1.500 so you would have to find a longer rod . yes i see it should be 230 crank and not 250 cid i slip on it ..... it was a long day making wrist pin bushing and boring the pin end of a set of bbc folwer rods
