that has the stock style cap and doesn't look as good as the ones I bought. I mean they look the same but on close inspection these look better and they have the good 65k coil, also cheaper....

First and foremost...... Rick said it all...... He has experience with them. Listen to him.

Second, you can't tell anything at all about those distributor caps from that picture.

The #1 most important thing about a cap is the ridges inside the cap between the terminals.

Spark misfire travels along the surface of the plastic, and the ridges make it twice as far between the terminals. Cheap caps have less or no ridges.

I have a ProComp distributor in my '78 Malibu 355 eng and my dad has one in his '80 Malibu 350 both engine are built and run in the 8's in a 1/8th...and we haven't had any probs with these distributors we have even bought a couple for some guys we work for an they all work absolutely perfect great performers. My opinion when you pay big money you buy the name not the product...we have bought several name brand things it perform like junk and used cheaper products and had great luck with them.

That's the cheap one, yes it had directions along with a lot of other stuff the ebay guy said they don't have. I just don't like misleading ads like his, I also like the best product per $.
MSD has it's time and place, a 12 second ride is just not really in the need for it when a $50 dizzy will do the same thing.

And if some say this cuts into MSD's pocket, well it probably does. and I'm not against it in this case b/c this is basically an GM HEI, not an MSD copy.

and look at the PP intakes. I bet you talk bad about them too. In my opinion the edelbrock I just bought, wish it was a professional products after closer examination. getting off topic, edelbrock vs PP, well then how do you feel about Holley vs Demon? if Demon was $75 a carb instead of $500 would that change ur mind??

Thanks Rick. I know there are a lot of "look a likes" out there.

If mine dies, i'll be the first to raise a stink for sure.

We all need to keep in mind that these are fairly new on the market and only time will tell if they hold up or not.

i have to agree the american made stuff has went to crap. they factor in the failure rate on everything made in american. atleast the foriegn stuff is just built cheap not built to break. everyone said PP intakes suck but they outflow edelbrocks and are half the price. everyone said they don't fit but mine went on without a problem at all. blows me away that the average honda or toyota runs for 250,000 miles and the average ford/chevy/dodge is lucky to make it 150,000 miles. its why toyota is about to kick GM out of the #1 spot. people remember all those cars they bought back in late 70's thru the early 90's that would crap out in no time from the big three. i say buy what works and heck with all that "buy american" crap. if those "building american" gave a rats butt about you they would build a better product for you to buy not something that breaks 2 months after the warranty wears out so they can sell you another one. spend your cash where ya want but i say foriegn doesn't always mean bad. as for the jobs all going to foriegn sorces blame the unions. i wonder how things will be once the minimum wage jumps up to 7.25 an hour. should be interesting to watch.

I bought a cheapo billet no frills dizzy off ebay for less than $50 not long ago. Entire dizzy with high V coil, weights, vac advance, cap rotor etc.

I took it apart and used only the guts (shaft, gear, rotor and cap). I didnt use the weights, locked out the advance, and disabled vac, used my MSD coil and MSD6A and timing computer. Ive run it to over 6000 a few times with no problems and my timing is dead on. So far. Its in my street 383 Stroker. I've never removed the inner shaft from a dizzy housing so I dont know if there are bearings in there??? Something in there allows rotation.

I keep wondering when this cheap thing is going to explode but let me say this: Compared to my stock GM dizzy which I replaced many years ago, this thing is FAR FAR better in quality. I hate to say it but I think the days of american "cast metal into a mold" are gone. Somehow they're able to produce some pretty good quality stuff overseas for real cheap.

The cap and rotor plastic are better than my original 86GM setup, the HEI stuff inside looked good enough, the lower gear seemed pretty good except that it had rounded corners are opposed to flat edges that my old dizzy had. The coil, Im sure, is truly high voltage as it states. Its just simple wire winding.

Granted, Im using MSD to do all the timing but the thing spins good so far.

One other thing I did notice was that the ADVANCE mechanism does not advance as far as my stock 86GM did. The original part had a longer travel for mechanical advance due to the mechanism. The new dizzy had a visibly shorter travel but since I removed it anyway I have no idea what limitations it had.

I'm running one of the 65K units off ebay and it is good for street driving in my 71 GMC 3/4 ton but I don't know about how it would be for racing.
So far so good as far as daily driving 60 miles a day and I just finished two 400 mile trips with it.

I have about 10 K on it now and will have to wait and see how it holds up.

Ebay Chinese 65,000 volt coil and HEI Distributors

Respectful of those that swear by Pertronix, MSD, Accel, original GM etc., I have bought 5 of those Chinese Billet Aluminum Distributors, Cap, Rotor, Coil from $35-58 complete, ready to drop in on eBAY over the last 8 years and have had no trouble from them. Of course I did not go for 100,000 miles yet on them. Meanwhile the GM correct Corvette Coils all had clunky worn shafts, and some 4 pin module failures. It is not a perfect comparison, since the Chinese ones fired up like champs and were brand new, but then again, you can buy 3 complete units and get all parts for the price of the GM, MSD, Pertronix, Accel.

My 1971 454 Corvette had a Pertronix setup with the $70 4pin multiple spark module and that went out in my driveway. I assume it was old, not junk, just old. I carry 2 $10 modules at all times now from eBay. My 1971 350 330 BHP engine had this sweet lope that I thought was a cam, until I swapped the distributor for the Chinese one and the "lope" disappeared and the power went up 50%, as I climb a hill immediately from my driveway. The correct GM one was clunking and loose as a goose.

These 65,000 volt HEI distributors displayed a super hot purplish white spark to plugs, not a weak orange spark, and until one fails...I will go with the cheap and buy extra. Used them on 5 C-3 corvettes, and just put the number matching stuff in the garage and then in the back of the car if you sell it to a buyer that whines about number matching.

Some Chinese units have see-thru caps and that is a delicacy to me.

You can install a 60,000 volt coil but the ignition system may not require but half of that voltage, even with 11:1 compression ratio. But it sure looks bad-*** when you open the hood.

Ignition Accuracy is your goal, not high voltage. I installed a Pertronix module in my 1963 Pontiac distributor in 1996 and it was still running great when I sold the Catalina in 2013. I made certain the Pertronix Hall effect shutter wheel was perfectly attached to the distributor weight base plate with no more than .010" clearance .

I have Pertronix I Stock Look distributor, Pertronix 7mm Ignition wire, and a NOS 1968 ACDelco coil firing my 1962 Chevrolet Bel Air with a 327 L79 engine, 3.36 Positraction and a 4-speed transmission. It runs strong and pulls hard to at least 6000 RPM. That will peg the speedometer in 4th gear with 3.36:1 gears and 8.00x14 Coker B.F. Goodrich tires.

It's not the voltage so much as current duration of the entire package. Virtually nothing beats stock GM HEI magnetics, module, and coil. So if that's what you have now, then don't buy a no-name, cheap Chinese imitation. But if someone has convinced you you'll gain more power by doing so, then buy a spare.

For me, the aftermarket choices would be MSD or Proform, but absolutely NOT Pro Comp or no-name.

If your distributor is OK you could just go this route: GM HEI black distributor cap & rotor set SBC BBC replacement 65,000 volt Chevy | eBay I did because I had a fuel leak that caused a small fire and trashed my HEI's cap and wiring it's working fine.
