Yes they do but.......do these blocks use the step nose cams???
what i was getting at was more that the gen-v was equipped to use a step nose cam;Yes they do but.......
You can use either cam in all BBC's they all have at a minimum the bosses for the thrust plate bolts & the majority will be drilled & tapped
Almost all early blocks were drilled for the factory gear drive thrust plate so the "step nose" is a drop in with the correct timing set
