First of all I want to thank Dirt Reynolds for the info!! Made my mind up on vortecs! I picked up a short block from a fella, 80-85 350, 2 bolt mains with an unknown cam, flat tops .030 over, .020 on the mains and .010 on the rods as a trial run before I put all my good parts together on a nice 4 bolt main block. Got some old vortec heads for cheap (906s but who cares) did springs and ghetto grind, replaced bottom end bearings, de-glazed cylinders, .041 head gaskets should put me at 9-9.2:1 or so. Gonna put a 2400 stall behind it with a TH350 and 2.73:1 gears out back. Not sure what to expect with an unknown cam but what's life without risks?? Anyway, thanks again to everyone that contributed to the thread! EDIT: Found a great deal on a new Comp Cams 12-242-2 cam!! Cant wait to fire this thing!!
