Nor Cal CJ5 1972 was the first year for the V8 in a Jeep. The 304 was an odd duck that year too. Lots of 1972 only parts.

If that photo you've shown of a 360 is in your Jeep, then that is what you have and someone surely swapped out the original 304 motor.

BagusJeep The VIN numbers were not put on the blocks and the cast numbers were shared between years and displacements. The only other way of checking is to find the cylinder head cast numbers, which were year specific, and looking for dates on the manifold.

No 360 V8 was supposed to leave the factory in a CJ5 but that does not exclude a dealer fit or a little experimentation at the factory. Replacement / service blocks were often produced for replacements without any number cast in the side, but that may not be a rule.

However, if you find the heads are a different year, it would most defo not be a factory 360 and not a "holy grail" CJ.

CrustyCJ5 Yea from what I understand the blocks are the same, just different bores. Correct, the displacement is cast right under the driver side mount.

Yes, if the original build tag was still on the passenger side valve covers, and you knew how to decode them.

But I get what you are saying. The 2 engines look identical.

Yup, the displacement is cast into the block, but it's not easy to see when the engine is installed.

W/S wiper motor should be on the outside. Wipers are 180* out but if the PO used the original wiper motor on the inside they will run backwards. No sweat it they work. It should have low back seats too. Front of frame and shackle brackets need to be inspected closely.

Please fill out your profile so we can know more about you.

Good luck!

Ah thanks..I got hung up on the windshield frame and missed the jeep logo position. Those 72 to 75s are definitely unique.

CrustyCJ5 Yea the windshield does look like it's been swapped from a later model, the original paint colors do not match up. The VIN matches a 1972 CJ5 304 w/ Toledo 3-spd/LHD.

How's the frame, check for rust and possible patches.

CrustyCJ5 Thanks for the reply - Agreed I'm skeptical it's a factory engine, going to dig in this week to look for evidence of a swap. Yes the wiper motor is mounted to the windshield frame bottom left. Frame and body are in surprisingly great shape (besides the paint color ) which is one of the reasons I picked it up.
