I tried the seach to find information on this, but couldn't find anything. I'm looking at replacing the 170 in my Mustang with a reman 200. I'd like to go with a post-'78 engine for the hardened valve seats and larger valves. I have found a few engines in the 80-83 range, but they have the low mount starter. The problem with that is that I can't find headers for engines with the low mount starters. Do they exist?
