Help figure out what engine was installed in sons F100?

to see if your engine is a 289. all you have to do is pull a valve cover. the number 289 is cast into the head. it,s that way on my 67 Mustang.it will also say 289 if you take off the intake manifold. the number is in the valley . very easy to see. the numbers are about 7/16,s or a 1/2 inch tall. you can,t miss them.

D2AE-6015-BA3

The D is for the beginning decade of production. The 2 is for the year that particular model started. The AE typically means passenger car. So this block started production in '72, but the date code says it's a '73. The rest of the casting number says 351W. As stated above, the foreign order on the intake is a dead giveaway, but so is the width of the block. The 6 bolt valve covers omit it from the Cleveland camp (8 bolts.) it looks to have been updated to a spark box ignition from points. I can probably narrow it down to exactly what it came out of and horsepower, but in off to bed. 2 bbl Windsors in '73 were rated below 200 hp, but can be livened up pretty easily.

If your tranny has a divorced bell housing with an aluminum gearbox, it's a C4. Divorced with a cast iron gearbox, FMX and an integrated gearbox & bellhousing, you have a C6.

The transmission we took out due to it failing with horrendous noises, had the top of the case broken off. It only had the 2 bolts on the lower part of each side holding it on. I've had a heck of a time finding another we can use for a core for rebuilding. Finally the tranny rebuilding shop found one, but only just before a guy contacted me and said he has both a 351 and a C6 with 47k miles on them. Still mated together when he removed them from the truck.

My son's engine had even, but low compression on all 8 cylinders. It idles OK, but didn't seem to have much for power the little bit we were able to drive it before the transmission stopped working.

Hopefully the tranny shop didn't order a rebuild kit so we're not committed to spending the money there and can instead get this engine/trans combo. Waiting to hear back from the tranny shop about that.

Did a mid-80s 1-ton Ford come with a 351W as an option? Looking on Wikipedia, it appears so. Wikipedia says it came with a 2bbl or EFI. The guy didn't know if his engine had a carb or EFI.

If we'd go for the mid '80s engine, are there any worries that it's been sitting in a barn that long? Rust in the cylinders? Should we stay away from something like this?

It mostly depends on the climate where the engine has been sitting. A lot of temp swings can cause the metal to sweat...therefor, rust. If it's been sitting with oil in it, that should help ward of rust. A mixture of Marvel Mystery Oil and Automatic Transmission fluid (50/50) poured into the cylinders with the plugs out will help lube and free up the rings. This can be used for either engine. Crank the engine BY HAND to allow the mixture to contact as much area as possible. Obviously the engine sits in a V shape, so gravity dictates what gets contacted without help. If you have the engine on a stand that rotates, that helps a bunch. Otherwise, compressed air can help spread the lube around.

A mid 80s 351W in a 1 ton is absolutely possible. It probably would have smallish intake valves, to help with torque, but it would definitely have hardened exhaust seats for unleaded fuel. The '73...not so much...though it's possible, not likely. Fuel injection came in around '86 or '87 for the truck engines, but the cam will still be flat tappet. It will have non-adjustable bolt down rockers...your '73 may as well. There's no worries with this style, you just can't run big cams or prolonged hi revs. There are bolt down roller conversions that work well for a little over mild builds. Windsors are capable of good hp numbers with little effort.
