Laying on your back looking up at the engine, passengers side rear next to starter there is a ridge along the block just above where the oil pan bolts are. Bring a tooth brush soaked in gunk engine cleaner or spray some carb cleaner on the casting numbers and wipe with a rag.
You only need the first two symbols;
C9XXXX = '69
D0 = '70
D2= '72, ,etc.
ok i checked under the manifold on both sides and i couldn't find anything. i'll have to scub it down like you suggest because there is some gunk up in there. the only numbers i can find are on the manifolds themselves and one on the back of the water pump. on the p-side manifold it starts with D10e-, on the driver side C80E. the water pump says C80E-D, and of course there is a long one on the intake manifold. I never thought it would be so tough!
The casting numbers are on the block are behind the starter. You have to remove the starter to see them. You will see numbers that look like this C90E-8015b. The first number will tell you the year. You do also have to remember that ford sometimes put engines left over from the year before in their cars. To truly tell if it is the original engine a partial vin number is stamped on the rear of the block on the passenger side right below the head on a flat spot on the block. Hope this helps.

Reason: wrong info
ohh ok i guess i have to suit up, brave the cold canadian weather and take the damn starter off. The numbers in the door indicate that it was originally a 302. I was assured when i bought it it had a 351. The guy i bought it off was a bit of a schyster tho. this is why i want proff and to be able to order the right replacement parts for it.
What's the long casting number on the intake? 302's and 351's have different intake manifolds due the the different deck height. I think a 302 manifold is 9" wide where it meets the head, 351 being wider. You might also want to pull a valve cover to see what numbers you find there on the head (even though the 351 heads bolt on a 302). I know what's it like to have to work in cold weather so thought I might throw out some other options. Yep, the only way to trully id your block is to find that casting number just above the starter, should have 6015 in it. Even then, there were many different levels of either engines.
ok ok i know i'm an idiot.... took the valve cover off it said 302 on the heads. took the intake off for an upgrade, 302 stamped inside. took the starter off a year ago and the numbers plugged into the "how to rebuild a small block ford" book said 302 made in 69.... sweet!
Speaking of long numbers on intake manifolds, I was cleaning the sludge off the back of my 1969's 302 when I found this code stamped into a brass plate, riveted/glued? to what I would consider the block, but could be the very rear of the intake. It reads "Z 2730 V 128375."
Any ideas? I looked up Ford codes for both blocks and intakes and couldn't find a code that started with a "Z" and looked like this.
That's the transmission to the left and a red/grey intake to the right. Intake is red, block is blue/grey, carb is 2BBL, water pump on passenger-side (if that helps, at all).
