going tomorrow to work on my uncle's truck, just the "work truck". 1979 Ford F-150 Custom with a 351. He thought he had a 351 Cleveland in it, becuase some friend told him if you have X number of bolts in the valve covers its a cleveland.

anyways, went to Napa they had two choices, 351 Windsor and 351 Modified. I looked at pics and the fuel pump for the 351 windsor looked like what I needed (by the way, have to replace the fuel pump on it).

so what I'm wondering is, what visual indicators are there to tell me what the hell the engine really is?

Thanks guys.
