Hey, I wanted to throw this out at you guys. I just bought a 351W engine and transmission last night from a friend of mine that supposidly came out of a 1969 Torino GT Fastback. It is a factory four barrel set up. I haven't checked the casting on the heads or block but it does have the four barrel intake with the casting C90E-9424-D (if I looked at it right). It also has the larger 18mm spark plug holes in the heads. I've read that these engines are not all that common. Correct me if I'm wrong. If this is the case I pretty much stole this thing from him. The only thing missing is the air cleaner assembly. I am thinking about rebuilding it to swap into the 1970 F100 I just bought last week seems how the 302 in it is on it's last leg. What do you guys think? Was this a good deal/find or what?? Oh yeah...I only paid $200 for the complete setup. AND IT RUNS!
Its hard to say if came out of just that model of car. If the block casting is C9OE-6015, it means it was produced in 1969 for a car not a truck. But most likely installed in a 1970 production car. Anytime over the history of that car, someone could have put a different intake on that block. Get the casting number off the heads and the block and that will shed some more light on your answer. Here are some specs on the 351:
CASTING NUMBERS
1969 351W engine block -- both 2 barrel and 4 barrel engines -- C8TE-6015-A
1970 351W engine block -- both 2 barrel and 4 barrel engines -- C90E-6015-A or C90E-6015-B or D
WINDSOR 351 V-8 ENGINE
Valve cover is held in place by 6 bolts.
Spark plug socket is 13/16 inch size.
Distributor gear is 1 1/4 inch diameter.
Radiator hose connects to water neck on the front of the intake manifold.
1969 was the first year a 351W was offered....passenger cars only. No truck used a 351W till the 1975 Econoline vans. The F series first saw a 351W in the mid 1980's.
Typically, Ford didn't use 4 bbl manifolds on anything except high performance engines.
I agree with above -- that someone could have swapped on the intake, but there are generally signs that this has been done - non-factory bolts, wrench marks on the heads, etc.
I'm not sure on the 351, but typically the 4 bbl motors had larger valves. That may be a sign that you have a HP motor.
All the 69-74 351W's had the larger (not by much though) 1.84/1.54 valves. 2 bbl and 4 bbl were no different. The 4 bbl motor on the 69's had slightly smaller combustion chambers and a 10 to 1 comp ratio. Casting number has no bearing on what vehicle the engine was installed in at the factory a block cast for a car or truck application could be used in either. All it really pertained to was what division got the engineering costs. A 69, 4 bbl 351W is a rare find now, especially one that's running and in original condition.
OK...where do I find the casting number for the heads? All I am able to find is 351 and WP inside the head. I'm getting ready to take some pics of this engine. From what I have found so far this IS a completely original 1969 4bbl 351W. I was told the car it was removed from only had about 33K on it. Going to take pictures...be back later.
If I done this right the links below will show you the casting numbers I have found so far. I read you have to remove a head and the casting number for it is on the bottom. Is this correct?
To see the head casting number you have to pull the intake and look under the ledge that overhangs into the lifter galley with a mirror, the casting number is right between the the pushrod holes. I wouldn't bother unless you're going to tear the engine down anyway, as I can just about guarantee from the other numbers you've shown that you'll find a C9OE casting number. I have two sets on these heads, one set came off of a '69 Eliminator Cougar 351, which also had the factory 4bbl. Wish I'd grabbed the intake as well, it was just laying there, but I intended the heads for a 302 so I had no use for the intake at the time...
Yes, all told, you've got a pretty rare motor there. Nice find!
(I'd probably toss that FMX Sludge-O-Matic though, were it me...)
On Edit: On closer inspection it appears the the original engine ID tag is still in place, attached to one of the coil mounting bolts tucked in under the water pump bypass hose. That tag should have all the info you need on it.

That's an awesome engine. Big port heads, 4bbl intake, good exhaust manifolds, stout block. You can get a stroker crank for cheap that uses cheap 302 pistons and have a really tough engine.
Definately a find, Ford chose to use the 351C as the performance engine starting in 1970. I used a set of the manifolds, along with the proper parts for dual exhausts, on a 302 in a 1970 1/2 Falcon wagon. With the 65 289 4V heads and intake, the car ran great and actually got better fuel economy. Open the exhaust ports up (grind off the emission "bumps") and you will be amazed at how well it runs
