2000 Pete 379 C-12 cam follower failure

Truck has 680k on the clock, supposed to have a fresh motor last spring. Past couple mornings had a slight miss, cleared up within 15 seconds didn't think twice about it starts ticking on the way home. 5 more miles got a dead miss, stopped it. Got a wrecker, get it to the shop dropped a cam follower got the cam too. Haven't pulled the head to check the hole yet mechanic is doing it tomorrow. Im thinking it's gonna be a quick 5K to fix it but my latest idea is to pull it and put a B model in it. I know an easier than said idea but man it would be cool. Anyone know if anyone on here as done the swap? The c12 has been a jam up motor but it won't hang with my b model wagon.

 

It runs great. It's got the big tune in her but I'm going to drop 5k in it or swap it out. That's the cross roads I'm at I've done some looking and all I can figure is different clutch and bigger radiator
