Ok thanks. That's what I was hoping I could do. I read somewhere that if I used the 273 crank I would have to get it balanced for the 318. So do I use the balancer for the 273 or 318 if the are balanced different. I do know I can use all the other parts including the distributor so I wont have to change the wiring. I will go with the Pertronix ignitor 1381a to replace the points and condenser, we did that on a 71 Dart.
