To the best of my knowledge if you are looking for a 231 v6 turbo crankshaft, then Dave England's question was not inappropriate. All 109 blocks came with the crank you are suggesting you DON'T want. They were 3.4 stroke with rolled fillets.
I have raw forged Buick Motorsport Cranks 2550008 which were used in the Stage II motors for Indy, SCCA, dirt track, circle track and 1/4 mile racing. These are the cranks used by Ingersol, Duttweiler and cut by Moldex and SCAT. I think maybe you are either misinformed or you don't know what you are talking about to form your question appropriately.
Dave has been in the game a long time, maybe you might be more explicit so he can help. Ifyou need a raw forging give me a call, they are nearly impossible to find. I have 4 left.
