I'm a School Bus Mechanic, here in N.Carolina, & at one time we ran about 50-60 1980 Chevrolet C60 School Buses(I purchased 4 of them myself). They were 350 powered, with Allison AT545 Automatics. The most common problem we had with them, was the cams, & that was only with about 10% of them. They had plenty of power. We still run 3, 350 powered activity Buses,'78, '80, & '81 models. So, other than the cams, they were pretty good engines.
