PertronixD104600 Black Cast Distributor Cap for Small/Big Block Chevy

Bought this distributer because of the reviews to replace a stock foreign distributer in my 68 Camaro with a 327. Out of the box the unit was packed well and looked like a quality casting. It even came with crimp connectors for the power leads. These wires were also 18 gauge and a quality primary wire. There was not much under the cap except a small sensor where the points would be. I oiled the distributor and dropped it in. It fit perfectly. I wired it to the coil without the ballast resistor. It has 12 volts to the distributer. I set the timing to 12 BTC and got another 6 degrees from the vacuum advance. The vacuum advance is adjustable. The engine runs great and it corrected the problem I had with the old distributer. For the price I paid on Amazon this is a bargain for a quality automotive part.I will report in a few months as tot he reliability. Buy with confidence.

Fantastic distributor for the price. Just finished a dyno session on a Chevrolet 355 ci. this unit was able to help produce 513 hp at 5,800 rpm. out of the box, perfect dist. for street performance. running, edelbrock 2x4 air gap intake, dual edelbrock 600 cfm carbs, 1.5:1 compression, Pro Comp heads, hooker pro comp long tube headers Milodon 7qt pan and Amsoil 10w30 oil. yes there are more expensive ones out there and cheaper ones as well, but I am convinced this is a great distributor for the price. And I have wasted money on both, with 48 years experiance as a state licensed journeyman mechanic. And a lifetime of street , circle and drag race experiance. This engine is now in a 27 Ford flat top Tee coupe, and it is a beast, weighting only 2,500 pounds. The engine now has 6,000 miles on it and still runs strongI have been using and installing Pertronix ignition parts professionally for 44 years since 1971. Mke sure you use only high quality spark plugs gapped .040 to .045, quality secondary wires, timming set properly for all stages of advance including total at 32 to 36 degrees. If you dont have the tools or experience to set it up right, shop around for a professional with the correct understanding and knowledge of all igniion systems to do it right,

The base of the distributor is not made correctly so the cap does not fit right . The groove that the cap is suppose to lock in to is to wide. The cap must be made in China because it is cheap and is not stamped with USA. The vacuum advance does not adjust correctly so I can not set the ignition advance. Works best with no vacuum hooked up but is still not correct. I was delayed on my installation time so the return time has passed.

AWESOME PRODUCT AWESOME QUALITY

It came as advertised. Satisfied with cost. Easy installation. Quality seems good so far.

Have yet to install and test, but part appears to be as ordered and has good reviews on other sites. I've use Pertronix Ignitors before on a couple of British cars and they cured ignition woes.

dropped right in my big block chevy and ran fine . Looks like the original .

Got rid of my old points dist & went with a electronic unit.

works and looks good rev limiter works great nice unit

what a terrible product. could not time the engine at all and spark was so erratic and intermittent the timing light couldn't even flash properly. JUNK.too bad I did not get to install it soon enough and ended up missing the return window. waste of money

Don't use this with a cast iron cam,
