Formula Junior A6 or A8 Camshaft Ground on billet.
A6 or A8 camshaft ground on a new billet. These cams are second to none, we have them ground for us to exacting dimensions. The original Cosworth A6 profile is the accepted cam for all four speed Formula Juniors. The Cosworth A8 profile provides more power and is acceptable in five speed applications due to it's smaller rev band. The cams are heat treated to 50 Rockwell and are compatible with our lifters tested at a 59 figure of Rockwell hardness.
