My new old truck

[Chubminnow]

I've never heard of a 351 small Ford big block, ain't no such thing I don't think. I think big blocks for Ford started at 390 didn't they? Chevy on the other hand made a 396 Big Block but they also made a 400 small block.

Tim you have a small block.

Ford made two versions of the 351, Windsor and Cleveland. To the best of my knowledge, one of those was a big block.
