Allstates used Delco ignition parts...with a caveat...the voltage regulator was an Allstate branded unit but made by Delco.

My 53 Allstate 4 has Delco on it, but I am not sure if this motor has ever been changed. The head does not say Allstate. It says Willys Jeep.

I noted Corsairdeluxe's comments on the 4 cylinder with interest. 2000 RPM under load maximum! WOW!! No wonder few survived for long. I take it that this same engine would have been in some of the Jeepsters, but in that application wasn't overdrive a given??  I can't imagine the 4 cylinder even back then in HJ not having an overdrive...

With standard OEM tires, overdrive, and a 4.27 and/or 4.55 rear axle, does anyone know what that translates into MPH? I'm missing a few figures, so can't figure it out on my own.

Another peculiarity of the 4 cylinder is the pitiful design of the oil filter. All of the oil sent to the bypass filter comes frpm a tap off the #1 cylinder oil gallery. The higher the rpm the more efficently the #1 cylinder is robbed of oil.

My '52 Henry J Vagabond was originally a four cylinder without overdrive. I purchased it ten years ago off ebay (many forum members may remember) and it had 39,000 miles on it, which I believe to be accurate (how many miles can you put on a four without OD?).  I drove the car 60 mph on the highway to take it to my brother-in-law's shop to have new tires put on it.  It made it there and halfway home! The number 2 rod bounced through the pan and the block.  When I pulled the engine, it was obvious that it had already been repaired once (the piston was knurled and there was no ridge on the bad cylinder wall). You might say it was converted from a 4 cylinder to a 3 cylinder first! A six cylinder engine with overdrive cured the problem and I've been enjoying it for 10 years now. I drive it on the highway at 65 - 70 mph all the time now. Drove it to a meet in Missouri Valley, Iowa a few  years ago, put 750+ miles on it on that trip and it did just fine. Since the 1951 four cylinders (and those '51s which were converted to '52 Vagabonds) all used the 41/9 rear end I did not have to change it when I converted it to a six with overdrive. If I had put in a six without overdrive, I would've had to also change the rear end to the 41/10.  Anyway, the car turned over 50,000 recently and has been great to own and drive. No regrets at all.

FYI: Early 52 Henry J's and Allstates were still Autolite Electrical. The change over to Delco came during the 52 production year. There are service bullentins that note the serial numbers and such on the Henry Js. I am not sure if there is any data/documentation on the serial numbers for the change over on Allstates. I believe John Hewett has an early 52 Allstate with Autolite Electrical.

The thermostat housing did not sell. I actually thought about buying it, Not sure if it was worth the 20 dollars that he wanted. But he did relist it for even more, 25 dollars this time.Does anyone know what these are worth?

I will say those thermostat housings are tough to find. Being made of aluminum, they corroded easily in cars before anti-freeze was the norm. They usually sell for about $40 so it's a good price. I too noticed it went unsold and was relisted for more $$$ - that seems a bit strange. They're not easy to find.

I think he relisted it at a higher price because i let him know that I would bid on it next time he listed it. BIG Mistake on my part.

Good for you!  It's nice when something sells at a good price and goes to the right place.

Well I just pulled the head off the 4 cylinder and there is a crack at the #2 exhaust valve. Looks like the 6 cylinder will be going in for sure. Has anyone ever tried the stitching tecnique on a block, and if so how did it turn out.

It's what I need, but it says local pick up and I live in Arizona. I have a 6 cylinder that I am going to install now. I just thought I would rebuild the 4 cylinder for a future project.
