Yes all you need is one hot wire to the coil.
If you have a ballast resustor on the car by pass it, you need 12 volts to yhe HEI.

Go to www.67-72chevytrucks,com and look around. Alot of people do this and there are instuctions and pictures to go with. One was actually a 250 they did the conversion on.

Dick Dale - that was right on, thanks for the link.

My project was putting a coil in cap HEI from a '82 250 into my 64 Chevy II 230. It went without a problem.
