Mine was a stock "109" ( casting number) block. The Buick GSCA (Grand Sport Club of America), has its own events and its own classes for all Buicks not only Turbo Regals. The class I was running the car in is TSM ( Turbo Street Modified) and the rules for this class states you must use the stock 109 block. I never had any problems with the bottom end. I did all the trick stuff to reinforce the bottom end , all the oiling tricks, gridle, steel main caps, after market crank, rods and pistons. My biggest problems was in the head gasket world. The stock block has only 8 head bolts and throwing 24 pounds of boost at it head gaskets just don't hang in there. Of all the gasket I tried the Cometic's held up the best.. The Stage blocks have 12 head bolts. Big help there...But for Stock Eliminator a stock 109 block would have to be used.. For a ton of info on these cars there is three real good websites to check out.
1) Turbobuick.com = mostly race oriented
2) Turbobuicks.com= street and mild race oriented
3) T6P.com= mostly race oriented
