Will GM HEI Distributor work

I was looking for a non point Distributor for my 73 inline 6, and by the pictures, it looks like an HEI out of a Chevy 292 will fit. I know the jeep distributor takes the same the Petronix part number as the Chevy Delco unit. Any advice on this ? Looking to buy Davis unified ignition Distributor if nothing else cheaper works.

Search for Team Rush ignition upgrade. There is a great article on the jeep forum about this. I have a 74 and was told the HEI dizzy from a 76 blazer with the I-6 engine will work, just need to swap the cam gear with your factory gear to keep from having cam wear problems. Will need mid 90's Jeep 4.0L wires with that. Plan to do the same upgrade myself this spring. I love buying parts for older Jeeps, Always fun to ask for this ford part and that chevy part and when the parts kid asks what your working on you say a Jeep. I have heard good things about the DUI systems also. Can also purchase dizzy, cap, rotor, coil and wires you need at the local Napa store for about $225

Summit racing makes a house brand hei for $ 150 cap included with adjustable vaccum advance and it has the correct gear on it. Cheaper than davis. I put one in my 4.2 yj. They also sell spring and flyweight kit's for around $20 so you can fine tune the advance curve for more power and better fuel economy. The davis might be closer on the curve out of the box but i doubt it. The only other reason the davis costs more is the hotter coil. Most fail to realize the coil will only use the extra voltage under high load conditions. Not all the time . It only uses the minimum voltage it needs to jump the plug gap. The overpriced over marketed high output coil manufacturer's aint going to tell you that. Any beginner's auto class at any college will teach it though . I'm not trying to bash davis. I'm just saying as an ase certified tech I've seen a lot. You know a certain brand of shoes will make anyone a pro basketball player too.
