'71 302 ID tag - Need help decoding

Hey guys. I recently picked up a '80 F-150 that's had the motor swapped. It's got a '71 302 in it now. Luckily the ID tag was still under the coil!
I'll provide a pic of the casting number in case that helps out too.

It reads:

302 C 71 9
1 - C K0291K

From tons of research I can safely say it's a 302, produced at the Cleveland plant in 71 and rev. 9, Made in March 71, however I cannot for the life of me find the code for K0291K anywhere. If anyone could help me ID this, it would be greatly appreciated!

Thanks guys!

Not sure why you'd need to know more than you know already about it. It's a run of the mill 71 302, they were pretty much all alike in internal parts.

Cause I wanna try to figure out what this came out of, just for general knowledge.

Well in 71 I'm pretty certain all applications be it pickup or car, all used the same long block assembly. About the only parts that would differ would be maybe the camshaft, and the alternator, possibly the distributor and slight carb calibrations. But at this point in time, there's no telling if the whole assembly is just as it left the factory, especially the carb.

It's definitely the same carb that's been on it.It was just as grimy as everything else and still has the tag on it which starts with D1. All I'm trying to do is figure out what the "K0291K" is about to tell what it came out of. Not sure if it's out of a truck, or a car, a motorhome or whatever else they were used in.

The oil pan will give you a clue too. If it wasn't swapped when the PO dropped it into the 80's truck. The 80's got a rear sump pan, the 70's had front sumps with the cars getting a 5 quart pan, the trucks a 6 quart pan with a longer sump (than the car pan)

I haven't been under it recently, never paid much attention to the pan but I ran the numbers on the carb ID tag and everything's saying Bronco/Econoline 100. I guess it would of helped to look at that from the get go.

Thanks for the help, baddad!
