Gotta put my 2 cents in. A 187 oil pan is supposed to work , I think. But some have had to adjust it w/ a hammer a bit . I ran a 800 double pumper on a hot 383 and a 406 (chevys) and loved it, tuning was no big deal . A double pumper will get worse gas mileage , but out perform a vacuum secondary carb. And yes , it will out perform an edelbrock too, not to say an edel. 800afb won`t work and work pretty good tho! If fuel delivery becomes a problem on an AFB , it can be drilled and tapped to make a dual feed out of it. If u ever see a 750 afb with dual feed , it`s probably my old carb.
