The distributor you need!
First it’s a very tight fit. The old coil has to be removed. Oil sending unit has to be removed. . All lose wires from old distributor tape up. 12 volt power supply form main switch. Dropped unit in. Installed cap and wires. Unit fired right up. Ran very good for about 200 miles. Started not wanting to start and running rough. Pulled cap. Main control module had shorted out.. after talking to a few people. My truck has to have the duel pickup distributor. Which controls the start and run. Over all very happy with the product, but very sad that it didn’t work. Found a duel pickup, installed and the truck is back and running. So if you have the due pickup. Go back with the duel pickup. It will save you a lot of time.

No spark replace distributer with HEI
Fit fine with plenty of room on the fire wall and works great bypassed all the problems with other distributer and electronics

Hard to beat for the money
Bought this to replace points and condenser on my '87 chrysler 5th ave. Stock 318. It is a tight fit and you cant turn it to adjust but the distributor does work. You also cant use the vacuum advance which doesnt matter to me but as soon as you hook it up it starts drawing vacuum. Overall a good buy for a beater like i have

Do you got the room?
Make sure there's plenty of room for that gigantic GM style cap. This worked fine for my non-stock 351 Ford, but my stock dodge 360, all kinds of stuff (throttle cables, oil sender, trans kick down) made it all but impossible without some serious hacking. Bummer indeed.

Works great for a little while.
Was not bad to install quite simple actually. This was installed on my daughters 1963 Plymouth. Worked great till it didn't one night as she was leaving a show around midnight her car just shut off. She called old faithful Dad to come fix it. I found that she had no spark. The problem was the clip that plugs in to the coil for the tach and 12-volt power supply had failed. The wire for the power supply had come loose from the clip. I was able to get it going to get her home. Further investigation found that distributer housing was also full of oil. This was purchased in April 2023 and failed on November 1st of 2023 with 1500 miles on it. Sorry for just now getting around to the review.

Total ignition replace
A total replacement of the ignition system. Power it up with 12v and spark comes out when it turns.

Tight fit.
Purchased this for 1987 Dodge Ramcharger. It is a tight fit. You can remove the oil pressure sending unit to get some room for the hold down bolt. I put the vacuum can on the right. inital timing is at 20. That would be ok, but this has a 20 degree mechanical advance which puts me at 40 all in. the body wont rotate anymore to retard the timing any further. I dont run vacuum advance. i will take it apart and see if i can limit that mechanical advance. Overall it's a great part and a good price!
