[V8Vairs] 4.3 vortec engine swap

[Carrine Bell]

I am attempting to put a 95 4.3L Vortec motor into the original location and reverse the rotation. I am pulling the motor from a junkyard and am getting the complete motor, computer, wiring harness, fuel pump, and subframe. I will modify the subframe to weld into the 66 corvair. Is there anything else I should pull? Also I know I need to reverse the engine, which needs a special camshaft, reverse starter, distributor and distributor gear. But do I need a special oil pump? Anything else I missed? The 4.3 has the same bolt pattern as a corvair (SB V8)
