Check you timing, too far advanced or too retarted, and you could run hot.

Does anybody know how to manually adjust the timing on a 4.0 FI engine? Ever since I swapped in a 4.0 head and the MPI on my 258 I've run hot. Even a three core radiator, new water pump, shroud, hood louvers, don't work. I can control it with an auxillary pusher fan, but that's a lot of work! I know the MPI is supposed to control the timing, but I've thought about grinding off the ear on the distributor and using the old hold down. Any thoughts?
