I have a 292 in my 66 GMC 3/4 ton longbed and am considering making the swap to HEI. I've been given a complete HEI distributer from a vehicle that was running until wrecked, but do not know which 6 cyl it had.

Will there be any problem if it came from one of the smaller 6's? How can I test the new unit befor installing it?

Any warnings, sugestions or tips from drivers with hands-on experience would be a great help


IF YOU DIDN'T TEST IT, IT DOESN'T WORK
