"goose": I have posted this message on 2 other boards and am still looking to fill in a few blanks. (the 4.2 V6 and the 221/.....351 boards) This is cut and pasted from those postings, I know it's long but I am trying to give as many clues as possible. I have received a few hints about the intake and block but nothing on the heads so far.
Thanks for taking the time, if you have any carpentry questions I'd be glad to return the favor!

I hope someone can help! I purchased a used motor which was sold (per the VIN) as a 1981 T-Bird 4.2L V8 2bbl OHV to install in the 1981 F100. My month-long dilemma started with a leaking carb. Since I knew that 2 rocker arms were cracked, I thought I would fix all at once. But when I ordered the parts for the 255, they do not match. No parts dealer, Ford dealers, or local engine rebuilders can help me id FOR SURE what the block, intake and heads are by the markings I have taken from each. Some suspect it is 302 or 351 (altho most folks have responded that it is NOT a 351), others think it IS a 255 and parts are practically unobtainable new. So here goes, be patient. I need to know what beast or hybrid beast this is. I have rods sitting in 60 weight oil and winter is blowing in Minnesota!
BLOCK: above starter: EOAE D3C with "15" stamped sideways to this number, "80" stamped on block, passenger's side by freeze plug near starter.

13
80 raised stamp, driver's front behind power steering pump

MANIFOLD: 0318
R EOSE 9425 FC 10W from left to right on back

F.O. off #1 piston: 1, 5, 4, 2, 6, 3, 7, 8
2,3,5,8 ports are raised on intake. Carb is 2 bbl that attaches to raised alum. intake, one hole through each port to back of carb, into EGR valve. 2 metal lines (one each bbl, driver's side larger) stick out of raised part of intake which carb attaches to, approx. half way up, appear to be vacuum lines, altho they are capped with rubber and always have been since it was installed in the truck and operating. Distributor in FRONT. Choke heater plate cover on pass:

DOAE
OATE with 2 bolts. Flat metal plate across from it on driver's side marked with a "B", 2 bolts. This intake manifold has a valley pan. In between the cylinder ports there is air space, it's open so you can see the valley pan.

HEADS: Driver's: has a "B1" stamped on outside corner, closest to pow steer pump. Under tappet cover, driver's side: 5 bolts, no washers, and 3 "allen-type" hex heads. A broad line, not an "I" or a "1" and 9753 in a circle. Large 78, this is most prominent mark. Again, the broad line and E4. Ford emblem vertical. Symbol: like a small "c" inside a larger "C", line, P (?, maybe smaller capital D instead of line and P) Heads have metal cooling pipe connecting each other together from back (firewall) EBR tube: F814B. Exhaust valves have removeable caps. threaded pedestal, fulcrum guide, rocker arm, fulcrum, attaching bolt (not stud). Any direction as to who might be able to, or other markings/features that might positively id these parts would be immensely appreciated.

 

I just wanted to let you know that I've been checking my books for the serial numbers listed....but I don't find them. E0AE-D3C would indicate a Ford engine block cast in 1980, but I do not have any reference to that particular engine. The D0AE-D engine was a 351C, 2 bbl. cast in 1970, but they quit building those in 1974. The high rise aluminum intake you mention sounds like an Edelbrock Victor hi-rise, single plane intake or some other type of aftermarket intake. Sorry, I couldn't help...I just wanted to let you know that you are not being ignored.

 

 

look up these sites and search through your edit drop menu under "FIND" , put in a specific casting id # , such as F814b.........
