Who knows Detroits? 4-53, 6V-53, etc?

I Ran Detroit diesels for 32 years and will run them the rest of my career they are simply the most dependable diesel ever made . I ran mostly 71's but if I was to put one in a truck it would be a 53 they turn faster and remember the noise a 53 will rattle the brain of even the most hard core diesel fan. a 453 is only 212 ci so a turbo really helps with power and noise .
