I would allmost absolutly say No,but our 77 mercs 400 had a small block pattern with a C-4. Of course that is rare I give it about a .5 percent chance of working. The 400 allmost allways had a big block pattern while the cleveland had a small block pattern. The 400 started in 71 I know we also had a 71 LTD with a 400.
