Well, I started looking at the engine on the '76 CJ-7 that I bought.. It has a 258, TH400, and Quadratrac. The VIN indicates that the engine is a 258 but I gues it could be a 232 - can anyone identify it?
On the driver's side of the engine is cast "322 4098" and also "E 8 1 7" , on the passenger side is "909 20"
I am thinking about turning this Jeep into a daily driver / light trail vehicle so I want to make sure the engine is good to run for many more miles. I did a dry compression test and got around 115 psi on all of the cylinders, except for #1 was 90 psi, but after adding some oil it went up to 120.
The odometer said 44,000 but that could be 140k or 240k, etc. I haven't gotten the engine fired up yet, but does anyone have any tips for assessing the condition of it before I go through the trouble of cleaning it up, new ignition and fuel systems, etc?
Also, looking for some input on rebuilt engines. Quadratec lists ATK rebuilt 258's for around $1500 including shipping, and Collins Brothers in Texas estimates $1000, plus shipping I assume. I don't have the patience to try to rebiult an engine myself.
Any input about this 258 would be appreciated. I'm leaning towards a rebuild since at least the ring in cylinder 1 is bad..
thanks!
