'77 F150 Engine Code Help

I have a 1977 F150 that I thought had a 400 in it, according to the VIN. When I got underneath it however, it was plain to see that it wasn't the stock motor. I had a hard time finding codes for the block, but I found two:

D4TE - located by the pass. side front freeze plug

6A29 - located by the oil filter

Can anyone help me figure out what motor I have in my truck?

If there's another set of numbers that I'm missing let me know.

Thanks

That truck engine was designed in 1974 and the block itself was cast January 20 /1976.

You didn't give me the suffix after 6050 - ? so I am asking myself what engine was designed for a truck in 1974 ?

How many valve cover bolts ?

Hmm...where else should I look? I'm not sure I know what suffix your talking about. It has 5 valve cover bolts, 2 on the bottom and 3 on the top. Thanks, keep the info comin!

Must be a 360.

You are going got have to measure the stroke or ID the crankshaft to know for sure.

The Suffix I mean should be an A or B

and read like this

D4TE-6050-A
D4TE-6050-B

as shown here
