easiest way to tell if it's a 351 is just look around the distributor, mainly looking at the height of the block where it meets the intake, right there 302's are very short, and 351's are much taller. so if you cant tell by looking at it just look down there and that should help you out some

you know i didnt count the number of bolts. hopefully that helps.
i heard an older 302 has more nickel in it.
but i couldnt eyeball any of them.
i know the first one was pretty wide and the thermo. was in the timing cover

most people dont know "codes" we know what to look for and we're telling you that.....
so i guess, head back and take some pics, the first one is probably your best bet on a 351W but be aware it won't be a roller cam motor

Count the valve cover bolts.
351W & 302 = 6 bolts
351C = 8 bolts
351W from 77 and up have 12 intake manifold bolts. A 351W from 77 and older have intake 16 bolts.
351W has the thermo in the intake. The 351C has it in the block.
That should help immensely.
