75mm since that's what they systemax is bored to. I'd go with a holley TB aswell, I like holley stuff personally.

RE: throttle body question?

Yeah probably right. Some people use 70mm on the Holley even though the opening is 75mm. So I dont think 75mm should be a problem. Too big isn't good so try 75mm and see.If not 70mm..
