If it were a 6 cylinder setup, it would probably work well...but part of the way it works is off tach cycles to time injector pulse width. So, if you're running a 6, this one in particular probably wouldn't be quite right. Howell does, however, make a 6 cylinder kit...and it's pretty successfully used on all the Jeep 6s.
If you had a basic 318 though, it would probably work wonderfully.
