Head casting numbers


Recommended Posts

Anybody recognize these head numbers? Supposedly on an early 70s non mustang cleveland block.

 

Sorry not a cleveland head, casting number is 1975 or newer.

Maybe a 351m/400

Do you have a wider view? Looking at the angle of the rocker cover rail, I'm thinking Windsor.

Both heads the same? That's a 351C block. How about a block casting number? Looks like M heads on a C.

 

How can you tell it is a C block and not a 351M block?

M/400 block has a raised up thermostat housing, and 99% of them have a standing rib to the side of the distributor

How about casting numbers in the starter area of the block?

Thanks! I think I would have 'noticed' the difference even if I didn't know why. That's a great way to quickly tell.
