351w identification
I need help figuring out what car/application my engine was used for so that I can easily find parts. Spent about 2-3 hours at different auto parts stores trying to figure out a replacement fuel pump but no one was able to help me without knowing what kind of car the engine came out of to punch into the computer to get a part number.
So I have a 351w in my 1970 f250. I wasn’t really sure what engine it was until I started researching this past week or so.
cast codes on the block by the starter are:
D4AE-6015-AA8
5F11
Etched on the block on the backside under the driver side head:
5C237845 ( I think this done by an assembly plant)
help identifying what car this would’ve been in would be super helpful or some tips on finding parts easily for my engine.

Looks like a June 11 1975 casting with 9.503" deck height as OEM. It was probably for the 1976 model year. Blocks are said to be left to "season" a bit before hitting the production line. Assembly of 1976 models would have started some time around mid summer as they were to be on the showroom floor in September.
Pick a mid '70s Ford. Most of them used the 351W at one time or another. Try Torino, that's a safe bet.
The pumps can't vary by much, and since you've got in a '70 F250, you should just try to match whatever is on there now, as long as it works ok.

Thanks! That definitely helps and I love learning new things about the history. I took the pump to all the shops but they couldn't get a match on it. Not exactly anyway.
I did some more research tonight and the stamp on the back leads me to believe the block was assembled in 1975 either in Ontario or Cleveland based on "5C237845" I mentioned earlier that was found on the back of the block.

Fuel Pumps
All small blocks from 1962 to end of production of carbed vehicles in the late '80s used the same mounting design for the fuel pump. So any pump in those years will physically bolt on and pump fuel, the differences are fuel line size (5/16" vs. 3/8"), orientation of fittings and what style - push on hose, threaded etc., and return line or not. Since your application is not stock, I would buy the pump that was used in your year truck with a 302. The inlet fitting should then point the right direction, and the outlet should have the correct thread.
Searching Rockauto is very useful for these non-stock applications due to the illustrations and cross references provided. A pump for a 1970 F100 with a 302 is listed as also fitting a ton of cars and trucks and vans from 1965 to 1974. Here is one style offered:
These ones are great for old vehicles with aged fuel tanks, as they will trap a ton of dirt and rust in the filter can and keep working. There is a sizeable replaceable filter inside the tin can housing.
There is also the plain type offered without the big dirt catcher.
