When most people think of the most hazardous occupation in America, few people consider that driving a commercial truck would be near the top of the list. But, annual safety statistics clearly identify that individuals working within the transportation industry have the second highest level of job-related fatalities, averaging over 900 deaths per year.

Having an issue with my 427 after dealer installed new exhaust studs. The first time they started it, it blew an injector. They rebuilt injector but it only lasted 3 hours.
