1964 Jeep CJ5 building questions

As it turns out the 1978 Jeep CJ7 I wanted to trade my vehicle for needed way too much done to it vs. what the guy told me it would need. So I am nixing that idea but I have found a 1964 CJ5 with the original f134 inline 4 and transmission. According to the ad the body is shot, but all of the running gear is good, engine, transmission, transfer case, axles etc etc. I am waiting to hear back if the frame is good/can be repaired, if so then I will be using it as a rolling chassis and build it back up. The price is $500.

Has anyone here ever rebuilt the f134? I have found the complete rebuild kit which runs between 600 and 700 dollars, or a completely remanufactured one will run about 2300. I am simply wondering about what type of mileage this gets.
as I have access to getting a 258, 304, or 360 bare block for 75 dollars and building that from scratch, not sure if the f134 would suit me. I am not worried about speed, and 65mph is pretty much the limit as to what I drive on the high end, and that is only if I use the highway for something.

I am hoping to hear from someone familiar with this engine, or this specific year CJ5 that has built one etc etc.

What I would like to do: Run 32 inch tires, no power steering, but I am not sure about whether with those size tires if I would need to do a conversion to discs or if drums all the way around would be fine. I am not building this to off road, it will be a daily driver except in the winter when it will be parked and I will drive my Land Rover. Would the f134 handle 32's or should I swap in at least a 258?

Also regardless of the engine, would the gears have to be swapped out in the diffs in order to turn 32's? The hardest part it seems will be when it comes time to put on a new tub, a complete body is right at 4,000 but at least the shipping is free hahaha!

The F134 is glacially slow compared to a modern vehicle. It'll only do 65 if you've got a step slope to coast down LOL!
For your intended use, I'd pass on that one.

Yup the 4cyl is slow But it was fine for the old CJ. I guess it all depends on want out of a jeep. $500 that is good for a chassis but if you are going to swap it out, probably would be best to get one that is running and driving. The brakes would need to be addresses. The original 9 inchers were not the greatest. They did work but you have to manually adjust them. Swapping in a v8 would be easier than the 6 cyl. The later CJs were stretched to fit the straight six. With anything it is up to time and money to make it work.

I have a '64 CJ5 that is all original with the 134 engine. It will only do 65 going downhill with the wind and then the engine will be redlined+. I would not recommend it as an everyday driver. I use mine mostly off-road and rarely get over 30. I do have the original service manual if you ever need some detail on how things come apart.

The older CJ's with the F134 are tractors with fenders. If that's what you want, then they're a lot of fun.

Depends on what speeds your looking at. With the right gearing, 55 is easily attainable.
Neither the 304, or 258 will fit well in the engine compartment. However, if your willing to spend a little more green, a V6 is the ticket, either the Buick or Vortec.
32's are fine, but will probably need a small lift to accommodate them.
Like it or not, you will probably be looking at both a steering and a brake upgrade. While both are adequate in stock form, they are, well, adequate (barely).
Highly doubtful on a gear swap. Most came with 4.88's.
Might want to do some pricing on body tubs and and fenders/hood. You might find the build more expensive than your willing to spring for.

the 1964 should have either 5.38 or 4.27 gears, iirc. my 1966 has the 4.27's. your d18 tc is pretty solid even with a mild v6 or v8 conversion. same for the t90 tranny if you don't abuse it. you're better off with a v8 or v6 engine. the chev 4.3 makes a nice swap if you want to maintain the rest of your drivetrain and advance adapters and novak conversions have everything you'll need for both v8 and v6 swaps from ford or gm. the longer straight six engines will require some body work, either cutting into the firewall or moving the radiator forward a few inches.

1966 CJ5A, mods are coming

I have the deep gears in my 60 as well with no over drive and it tops out about 45 on 29" tires. but it will do 45 up hill, down hill, sideways or upside down. it is a lot of fun though, but definitely not a daily driver.
