1980 K20 Scottsdale block stamp deciphering

[lil green]

I'm looking at picking up a mud truck this weekend, but for some reason the fact that I can't figure out what motor is in it, is kinda bothering me. I found the sticker on the inside of the glove box, and ran the VIN. the interior is out of a 1985 C10. so that was no help. Anyway, after a few minutes of scrubbing the block, I found a couple numbers stamped into the block. the only problem is I can't decipher what they mean. Even with google, I can only figure out the date it was made. Basically, I just want to know if it's a 305 or 350. Here's the numbers:

V1005TMH
C9F343573

Any help is greatly appreciated!

Thanks Guys.

id say 350

350. Don't think the useless 305 ever landed in 3/4 tons.

That's what I'm thinking, especially since it's got LT's and the block and valve covers are painted baby blue.

Oh, yea, it's John Deere green.




My 98 RCSB that I finally got the GMC grille put on.

Jesus Christ. Does the mullet come with it? Do you have to get teeth pulled upon purchase? Is there a cushion in the bed to your cousin on? I'm sure you can see where I'm going with this one.

Haha it'll get repainted eventually. I'm not too concerned about the paint just yet since it's gonna be an off road truck. however it will be getting a Dixie Horn and a Rebel Flag. Oh and the black barrel and pipe in the bed are a deer feeder. It also has hydrolic implement hook ups in the bed.

Look at the back of the block on the drivers side behind the head. The casting number is casted into the block there. It will tell you the year, what vehicle it came in, ci and 2 or 4 bolt main ect.
