53fordguy,

This is the firing order for a 312 V8 Ford engine. It was used in many cars and trucks in the late fifties.

There's a good site about Y-blocks www.y-blocksforever.com

Does it have those really cool ramhorn exhaust manifolds? It might be the larger truck verzion of the Y block, a 332 I think.

That was also the firing order for the 292's as well.

it look alot bigger than a 312ci its a monster but it doesnt have ramhorn exaust... it has the usual wrap around exaust that leads from one manifold to the next and then out to the exaust

Ford's "Super Duty" name originally applied to the 401, 477 and 534 gas V8's used from the late 50's until the early 80's in heavy-duty applications. I believe they used the firing order you have listed. These engines are physically huge.

One way to ascertain the difference:
Y-blocks (such as the 312) had center valve cover bolts.
SD's had perimeter valve cover bolts.

[53fordguy]

it has a huge holley 4bbl if that helps?

[benwantland]

Lots of engines have huge holley 4v's, whether original or aftermarket. Check the valve covers.

[redlightning]

Does it have two bolts in the center of the valve covers holding them on?

The 302/332 HD truck engine was in the LINCOLN Y-Block family. Discontinued in 1963.
