427 SOHC Parts


The supply of NOS items for these engines is quite limited. Although recently there has been a resurgence in interest and parts availability, there has only been sporadic cam availability. When we started building these engines in the 80s, it was quite difficult and expensive to locate good cams that had not been reground.

Over the years we managed to collect NOS cams for the grinds listed on this page. These were used for blueprinting and as comparators for a new production run. Because of the small quantities involved, a specialty manufacturer with extensive knowledge and prototyping experience was needed to ensure consistent high quality pieces. LSM System Engineering has graciously worked with us to bring the highest quality billet cams at reasonable prices to reality.

Extensive testing on the dyno and in the field has validated these products and as always, we stand behind them. If you have a problem with our products, it will get handled without excuses.
