Help Identifing
where can I find the serial number on my engine to confirm if its a W,C or M? And when i find it how do i tell what it is? We only realized it was 351 when the 302 firing order didnt work (uncle said it was a 302, its not). I would like to find the serial number and confirm my engine before doing any good work. I will also post this on the 351M/400 forum as well. Thank you all for the help

A 302 can have either firing order.
As per prior pose, 6 bolt valve covers = W series, 302 or 351W or any other 221-255-260-289. The valve cover shape is like so: /==\ .
IF you have six bolt valve covers, look at your block with one eye and this with the other:

ok so we kinda decided it is a 351W. 6 bolts, firing order matches a 351. I have another question, this engine has a serpentine belt. Its a 79 truck, so unless im crazy its not original, but i dont know what a good year to go with to order parts? For example, it needs a freeze plug. Is there a good year for ordering purposes for a 351W carb'd?

351W not available in F150/350 & Bronco until 1981.
So, if the engine is a 351W, it was swapped in.

Number dummy, I agree completely. I guess my question for clarification is when did the 351W start getting serpentine belts? and ill have to update the about me. Unfortunately the 78 is no more so now i have a hand me down 79 f100.

Dirtyferd, it has the ridge. And i dont mean any disrespect, but there has to be a more exact way to determine an engine, versus a number of valve cover bolts and if theres a ridge or not. there has to be number or something somewhere.

There is a casting number on the bottom of the block by the starter. That doesn't necessarily tell you the year of the vehicle it came in. For example, a 1991 truck could have a block with an 1989 casting number. There may also be an aluminum tag under a bolt on the carb, distributor, or coil. There are plenty of places for deciphering those tags, if you have one, online.

I didn't go through this whole thing but for example I found C4AE in more than one place. Two different engine series. So you need to know that first, then on to the casting numbers.

question guys. This same engine, has a 351 oil pump M-83 at autozone; but I thought the thermostat housings on 351 came out of the block? This one comes out of the intake. thanks as always
