Why didn't GM offer a 454 in 4wd 3/4 tons?

I guess GM made this one too, right?

As you see those, kick 'em my way. I'd like to take a look.

The 1st link I provided has expired unfortunately, it was however working in another thread when this subject came up several weeks ago. I'm sure people looked, no comment was made.

When I get these linked pics to work I'll post if you like...

Why not do this the easy way and post a pic of the VIN and/or RPO’s for the next K20 Sub w/a 454 you run across?

Seems like an easy way to tell what was in that particular rig from the factory.

I have no doubt you’ve seen them. I’ve seen them, too, but the one’s I’ve seen had originally came w/a 350 and somebody dropped a big block in it somewhere along the line.
