Engine identification
I recently pulled the motor from my 1984 f150. I know it's not the original motor since the vin claims it's a 351 windsor but the deck height is too low for that. The guy i bought the truck from said it was a 302, but I'm trying to confirm and hopefully figure out what year. I tried google but that went as expected. There's no shelf casted into the block by the starter and the bell housing area by the back of intake manifold is blank. I did find a casting number on the intake manifold itself, but that says it's a '78 351/400 modified which seems wrong since the bell housing is a windsor series not 385 series. Additionally the timing chain is not recessed in like the modified. So is there somewhere else i can find the date info? The Manifold says "D8AE"

6 bolts. Alright now I'm even more confused why the manifold says it's a modified

All "D8AE" means is 1978 full size car line, Engine engineering group.
Post 9 shows the water pump/deck relationship for both 302 and 351W.

302 and 351W valve covers are /==\, vs. (==) for most other engines.

D8 for 1978 is a revision date on the casting. The casting could have been used for a few years after '78. Theres a date code down by the starter area if you really must know.
Does it run ok?
'78 was still a dark year for power for all engines. Mid to late '80s the roller cams started to show up etc.
You probably know all that.....
If it comes to upgrading or replacing, there's plenty of info here on what to look for to get into the 200s+ for HP for very little effort beyond the basics. Ditto the 351W as to roller cams.

The easy button on identification is to simply post a picture of the engine, that is the best way to ID any Ford motor.
