Blocks ID help needed

I just ran the VIN on my 1979 F-100 Ranger (which I posted a week ago about buying it in non running condition) The previous owner told me it has a 351 in it. The VIN says it came from factory with a 302. I was disappointed with having the 302, it's nothing good expect to move the truck.

If it really has a 351, where can I find the ID or block casting on a 302 or 351? Will I have to remove something to access the plate/stamps?

There were no 351W engines factory installed in F series trucks through 79. A 351W could have been put in the truck since 79 though.

What??

Yeah, there were 351s in F series through '79 from factory! Didn't say which 351. My dealer bochoures says there's even an 351 engine as an optional engine.

Maybe I should clarify a little. The 351 was installed by someone and I wanna confirm it if there is actually a 351 motor in the 79. Hence my asking on here for help in how to ID the 302 or 351. I just found out the factory engine was a 302 but it's long gone, that if it is.

[font size="1" color="#FF0000"]LAST EDITED ON 15-Jul-01 AT 03:36 AM (EST)[/font][p]No, he's right there were no 351W's(W=Windsor) in those trucks from the factory. What your reading about is the 351M(M=don't ask!) which did. Sorry, I'm too tired to explain the difference right now.....

Check the firing order cast on the centerdome just ahead of the carb. If its a 302 it will start with 154..... and the 351's started 173..... If it starts with 173..... then you know its either a 351W or a 351M (M = modified, 351 cu in a 400 block). To tell if its a Windsor, check the number of bolts in the valve pan
Windsor = 6, Modified = 8.

Hope this helps.
