Cletis,
I'm a retired firefighter and we had '54 Chevrolet Brush Rigs with a 261 in them and a five speed manual transmission. They were good rigs too especially for our off-road work. Those were 6 volt units. Then in late '55 they bought two more with the later '55 second series cab. Still 261's but now 12 volt systems. All gave great service.
