    Hi!! I need to buy a new Head for my 1989 Jeep Cherokee Laredo 4.0 litre engine. I can not seem to find the engine casting number. I was told it is on a plate below the Head next to the dist. Unfortunatly, it is very un-readable. I got a partial number, it is 90IMX25. My vin # is: 1J4FJ58L5KL52300. Can you help? or send me a link to somewhere I can find this info?

    Thanks!!

    that is a poly 318. it is an “A” engine not an “LA”. the bottom end stuff is pretty much the same but the top end is completely different.

Also have a 4006530-400-11 and a 4006630-440-10, the latter of which is going to be built as a stroker for a 73 Road Runner. What can you tell me about the 400’s.? Would one casting be better than the other. I can’t find any information on the first number mentioned.

  49. Rick Dyson Says:

    I have a motor that was said to be from a 1959 plymouth, the casting number is
    148492932. The casting date is 7.21.55, and there is an A2 centered above the date. The tag front driver’s side of the block has “FA” above 11053, and T338*79026*. Any help with ID of this motor greatly appreciated. And, where can you look up these numbers? Every site I’ve found has mostly muscle car numbers. I’m planning on putting this motor in a 33 plymouth sedan, and need parts badly.

    Thanks,

    Rick

    I recently bought a new crated engine that has a casting # 4104230-318-4. THE SERIAL# is 3M318 0720xxxx. Can anyone tell me exactly what this engine was built for?

  51. jesse Says:

    I have a 1968 383 motor, the pad under the distributer says: D 383
    88
    R
    I understand this means ist a 1968 383 intended for Regular fuel. but I don’t understand the number 88.

    The underside of the engine near the strater/oilpan has the number PT383R22020294
    I understand this mean it was made in trenton, and should use Regular fuel, but what date is 2202 and 0294?

    Any help would be appriciated.
