I purchased what was listed as a High Performance Dizzy off Ebay last year for $40 bucks NEW and I had nothing but problems with it. I'm not sure why but I got timing readings all over the place from it. That could be just my experience.

One for a Ford 302. You want it? It's sitting beside my desk. I recurved it and went on a 200 or so mile trip. The longer I drove, the worse it detonated under light throttle. After we got home I took it for a 1/4 mile test and it ran like garbage afterwards - misfiring as if the spark was scattering above 3000 rpms. I put 2 and 2 together and decided the only thing to cause all of this was the dist shaft grinding down into the distributor which would cause the magnet to hit the pole piece causing the erratic fire AND advance the timing by rotating the shaft forward as it lowered. I pulled it out and BINGO. The shaft ate the top bushing causing it to drop about 1/8 inch. It may have 500 miles on it total. Luckily I bought it as an experiment and tossed my Mallory back in it.

Oh, yeah, to add to my story above, timing was erratic as hell varying 5 or more at idle. The Mallory you can't tell the engine is running with the timing light.

You get what you pay for, OP. I wouldn't put one of those in my engines. EVER. The distributor works with the camshaft to time your engine and provide the spark at the right time. NOT a place to bargain hunt.

I've bought 2 from a guy in Canada, Ebay, rebuilt, worked like a charm, decent price, IIRC about $65 complete with cap.

There have been reports (link supplied by artsvettes on another thread) of some imported HEI replacement distributors burning up the cap and rotor due to a high resistance center contact that passes the current from the coil through the cap to the rotor.

There are also several threads on the imported vs. name brand parts including distributors. Here's two:

Get rid of the Chinese module, they are crap. I put a GM module in for my neighbours Chevelle (he bought a Chinese dist for it off ebay) and it fixed the timing wander. Also check the pickup coil magnets make sure the points on the magnet are spaced properly, might be an idea to change the pickup coil too.
I also had to recurve the mechanical advance with a HEI advance kit (and a bit of precise grinding to the advance cam under the rotor).

Just start with an original GM unit and rebuild it with quality parts, you'll be mile ahead.

I know too many people who have these cheap HEI knockoffs hanging on the garage wall because they are crap.
