Did Ford produce any 351W with four bolt mains in 1969 that were possibly in a Mustang?

I have never heard of one. I doubt it.

No such thing, even four bolt 351C's weren't typical. You're going to have to pay big bucks from the Ford Racing catalog to get one new. There are siamese and non-siamese bore, wet or dry sump, cast iron or aluminum, different bore ranges and 9.2" or 9.5" deck heights. Lots to choose from though, which is good.

What are siamese and non-siamese bore?

Siamese cylinders means that two cylinders are together without water between them.

I knew that Ford made the sportsman blocks...well...they DID make some of them. I had someone to tell me they had a 4 bolt main Windsor and I didn't want to drive that far to see it wasn't.

Thanks

to make a correct response you must read the question grasshopper<G>. ford did not make production four bolt main 351 windsor blocks in 1969 or 70. they did make 4 bolt blocks in the 80's and 90's but that was not the question. i have seen some aluminum 69 blocks and one was four bolt while the others were two bolt and the casting was different so you could not just add caps. hawkrod
