Jim, GM catalog shows the following (sorry, I only go up to 71 on this): 6470424 - (type 40727) fits 69 All (396) 70 Chevelle w/Sp. H/Per. (396,454) 6470307 - (type 40768) fits 70 Chevelle w/4BC (396,400) (exc. Sp. H/Per.) 6470570 (no type number given) fits 71 Pass., Chevelle w/4BC (400,454) (exc. Sp. H/Per.) One of those two should work. BTW, the "type" is usually the AC/Delco aftermarket part number. If yours is originally an AC/Delco new or rebuilt unit, many times they have the "type" roll stamped into the edge of the mounting flange. I haven't used or changed a mech fuel pump in a while, but I'm pretty sure the sbc and bbc pumps mount the same and are interchangeable...more or less. It depends on the position, size, and number of lines involved. I would also imagine that the bbc pumps may have a higher flow rate, but can't prove it.
