    i had it changed on my 72 shortly after a rebuild and i couldnt be happier. gives a good kick in the butt when youre trying to pass someone on the freeway.

    i went with a stock gm unit. i beleive it was from a 75 year 350 model. just went down to autozone and told em what i wanted. my girlfriends dad did it for me and seemed to be fairly simple. cut a few wires, changed the connections, got new spark plugs and wires and that was pretty much it. took about 30 min.

    there is a guy on the board that does that. think his name is dave or dan? i was gonna go this route but i was in the middle of a rebuild so we just did the distributer the same time.

    the difference was night and day on my car.

    The stock HEI will be a big improvement. Total advance will increase as well. Daves distributors will be a larger improvement according to those here who have one. I guess it comes down to what you have to spend on it right now. My stock unit works great on my stock engine, however, when I do the cam an intake swap I'll be ordering a high-perf unit from Dave.

    I used a stock HEI dizzy I bought on e-bay. We replaced a few parts, and put it in.

    Now my points weren't in the best shape, but after installing the HEI, the car started much easier.

    Hooray for HEI. I swapped my points for HEI as well (thanks to Dan's,
    Floydsbuick, suggestion).

    Another Dan suggestion was to make sure you gap those plugs. I've got mine at 45.
