I have an 88 F150 that originally came with a 351W and C6. The PO had replaced the engine with what he said was a 302. Now, my question is is there anywhere else besides by the starter where the casting number would be? I've scrubbed and scrubbed and still nothing there. The reason I'm asking g is because I was chasing a misfire issue that ended up being the wrong plugs because I thought the motor was out of an 88 but I believe it is actually out of an earlier truck. I put spark plugs for an 85 in it and now it runs like a dream. I'm just wondering where on earth the number is so I can ensure I get the right parts when needed. Thanks.

 

If you're looking in the right place and don't see any numbers, then I would venture to say that you don't have a 302. They've been stamped in the same location since at least the 60's I'd say.

This will help you figure out the engine family and possible displacement options of your block. Then you can google where the engine stamp should be. A lot of the fords, but i dont think all, use the location near the starter though, so I still think that you are probably missing something, even a date stamp would help.

 

Its definitely a Windsor block. It does have a date code on the the block that is for an 85. I bought the plugs for an 85 and it now purrs like a kitten. I'm just wondering if the engine was reman would they grind off the the casting number.

 

Hmm hadn't thought of the reman possibility. I don't see the reason they'd grind it off, but if it's really not there then I guess anything is possible.
