I have a large hei that came off my 383 in good condition. I also have an Accel lrg HEI that came off a 454. I called Dave the dist guru and he said throw them both in the trash. He said to get a used aluminum chevy dist and he will dial it in for me.
My mechanic said try one of the HEI's to see if it works. Anybody have any suggestions?

May get better answers in the Performance section. The guys over there have more experience.

Does Dave have anything that he wants to sell you in the place of the trashed HEI's? Your mechanic seems reasonable. Is anything wrong with the HEI's that you have? They can be repaired pretty easily with off the shelf parts. Try some of the trouble shooting tricks in the HEI Tech Reference section here, or just put one in the engine and have at it. The large HEI should be fine unless you have a clearance problem or do not like the looks of it.

They are probably fine. The biggest problem is clearance. I put one of them with wires on the engine and it was right up against the firwall. I would rather have a smaller Hei or diff set-up that has more room to move........bk

Dave went a little far by telling you to throw them in the trash, you should probably sell them. The problem as I see it is that those aftermarket HEI's need to be modified to restrict the vacuum advance and are not set up to your engine's specs, they don't have your spec's and set them up to a predetermined spec, Dave uses your engine's spec's and intended use to set the dist up and if I read the post correctly, he asked for an aluminum dist core to be sent to rebuild. If you have restricted space or want to keep it looking original, Dave is the one to use.
