I just measured my edelbrock aluminum intake for my 400m the total width is 12-1/2" at the front and the front set of bolt holes are 10-5/8" c-c. the cleveland intakes are at least an inch narrower. I would have mentioned this earlier but i forgot i still had that intake lying around. I hope this helps you

i think you are a little fuzzy on the numbers? D1AE is a common casting code for Clevelands and 400's, probably W's and others. the other number you have there, 6U12-C, i think that's your casting date code. the "U" doesn't make sense though, that digit is for the month of the year. A is january, B is febuary and on. I is not used. M is december, there aren't enough months to get a "U", could it be something else? to differentiate a C from an M, i would look at the front of the intake right behind the distributor like F150daniel suggested. most but not all M's have a 1" high rib of metal standing up to the right of the distributor, and the intake is a good 1" higher than the top of the block near the distributor. a Cleveland intake is about flush even with the top of the block near the distributor.

OR the N can mean
V8 390cid 2BBL Carb 1973-76
Because my truck is a 1977 shouldent it be a 390? I am trying to find out what it is. I just bought it today. Then some people are telling me Ford used a 351 Modified? What does that mean? How do I know what my engin is?

Last year for the 390 or any FE was '76.
A 351 in '77 would be a 351M.
The 351M is a short stroke 351 cubic inch version of the 400 engine, which was introduced in 1971. 400s and 351Ms are identical externally.
8 cap screws hold rectangular valve covers.
A 351W would have trapazoid shaped valve covers with the ends like so:
/----\ and have 6 capscrews holding them on.
A 351C would not be stock or even likely, as they stopped production in 1974, and were never factory installed in trucks other than the Ranchero.
You can get more info from other threads in this forum.
Bad news: 351Ms are pooches, underpowered, and no one likes them.
Good news: They last a long time, and can be made into a firebreather if you like.

are you sure it's not D1AE ?
too bad the sticky post about How to ID Ford Engines disappeared
is there a sticker on the valve cover?
you'll have to count the bolts on the valve cover, is the thermostat housing on the intake or the block, are the fuel pump bolts vertical or horizontal, exhaust bolts horizontal or diagonal, timing cover aluminum bolt-on or part of the block?

im trying to order a rebuild kit for the engine. i went to go get new spark plugs and the ones that i got that should have fit were way toosmall --Motorcraft sp450-- thats what it should have called for, i found the right ones in autolite, and they were apparently for 400 heads, i checked the fuel pump, its not a cleveland, but that still doesnt narrow it down much, its either a 351m or 351w.
