Can anyone confirm that the fuel pump boss on a 235 matches that on a 283, or a 350 (ie., same gasket would seal on both the L6 and V8 engines)? If they are the same then I can buy a cover plate listed as fitting a V8 and not have to make one for my L6 if I go electric fuel pump. Also, a machined cover will probably fit nice and flat onto the boss giving a good seal. Thanks.
