Description:

I'm looking for an 86 or newer Vortec style block with 4-bolt mains and 1-piece rear seal.  I need a block or complete short block if it has a forged crankshaft.  I'm in the Sacramento CA area but will pick up within a reasonable distance.  I would need to see it to purchase it. Looking to build a 350 - 383 with aluminum heads and small (5-7 lbs. boost) supercharger.   Thank you!
