Now, maybe you were thinking of putting your top end (heads up) onto the '03 block and use the transmission etc.  You'd likely need to measure and modify your driveshaft to fit appropriately. _____________________________ Kyle- My Restoration Projects Please Do Not PM for Tech Help (in reply to JoPre) Post #: 5
