Pushrod engines are the preferred choice of many in the performance and racing world because of their simple design and low-end power capability. OHV engines offer many advantages due to their smaller packaging and larger displacements compared to their OHC counterparts. Much of the advantage comes down to one component – the pushrod. While relatively simple on the outside, there's more to a pushrod than meets the eye. They can be a weak link in your valvetrain if you don't set them up correctly or choose the right material and size for your build. |
