Cheap quick fix:
you got to grind out the center 4 bolt's to make it work or you have too put 350 EFI head's on your old carbbed block. . .
proper fix later:
other wise Jeg's offer's and intake for both swap's EFI to carb and Carb to EFI. . .
Imagine that another 350 fail's. . .< boat anchor :hammering:
