Was looking at distributor and was wondering if a guy was change the cap on one would a dist. from a 6 work on a 8, or visa versa? Don't know whether they make the same rotation, is the bottom gear the same or what , just a thought?!

The 6 and 8 cyl HEI's are different. They have a pickup coil inside that tells the dizzy when to fire. The 8 cylinder has 8 points on the pickup coil and the 6 has 6. now possibly it would work if you change pickup coils, but I don't know for sure.

You're better off just getting the correct distributor. Like O'l Buck said, a 6 dizzy has 6 points on the pickup coil, where as an 8 has 8 points.

The distributor shaft length between the 2 are way different. You'd need to know a good shaft stretcher
