well guys after alot of thought and kicking this back and forth around a bit and looking at the money end of it I think I am going to keep a 2.8 but put the 4.3 TBI and bore the intake and redo the exhaust. I REALLY appreciate all the info for the 4.3 swap and it still might be something I will do in the future after I get the drivetrain in order. I just dont want to spend all the loot on the engine, I think alot of the little things will eat away at the budget for the engine swap. Once again though I really appreciate the info and your guys help on the matter.
