Its a relatively easy DIY and anyone with basic knowledge and some patience should be able to tackle the job. Altering valve durations can alter the power band and on most engines the exhaust and intake durations do not need to match, although most cams and tuners use matched pairs there are some advantages to extending the intake or exhaust durations. The M272 uses a 90 V angle like most V8 engines. The Mercedes M113 engine family made its debut in 1997. It was based on the similar M272 V6 introduced in 2004..
