YEs, talking the early small block and MarkIV big block. Yup, figured the lifter diameter was the same so why not.
BUT, i went out and looked at the block this morning and noticed i would have to grind clearance around one of the lifters (dont remember if it was exhaust or intake), for the link bar to go around it, it would mean taking alot out of the block in the edge of the valley. I'll have to see if i can get a pic of the block later to show. I just dont know if it is safe to grind that much out.
