That is correct for the stock unit, but OP said the motor has been replaced with a crate motor. Which could mean almost anything under the sun could be in that engine bay.its a 351

Will look in PERSON as soon as I get back up to SC. All answers have come from a helper at my shop looking for me. I should be back tonight.Here's one way identify between 351m and 351c.
On a 351m there is a ridge/fin type deal cast into the block on the RHS of the distributor and running between the timing cover and intake manifold. No ridge = Cleveland.
I am 100% sure it is a 351W HO. Told by the Ford Dealer and they guys that race these motors, since he wanted yo buy this one and give me another, NO WAY.As stated previously
8 bolt valve covers are Cleveland
6 Bolt valve covers are Windsor
Thermostat Housing in the block is Cleveland
Thermostat Housing on the intake manifold is Windsor
Bottom of intake manifold at the same level as the distributor adjustment bolt is a 302 Windsor
Bottom of intake sitting on a cast ridge behind and slightly higher than the distributor adjustment bolt is a 351 Windsor (i.e. taller deck height)
