I bought new frame mounts for my 69, I purchased the ones for the 302,or 350 hiperf because they are a little shorter and I am concerened about hood clearence. What I need to know now is which block mounts do I use and is there a difference?
Yes there is a difference. I got the correct ones from D&R classic. Along with the correct frame mounts. You dont have to get them from D&R but beware some guys will try to sell "these that work". Then you've got clearance issues down the line. I think David Pozzi has this info on his site.
