Hi All! I have been going through my collection of Mini parts and have come across a complete rocker assembly. The numbers on the individual rocker arms are: 12G1222 I am not familiar with this type of rocker and I have a hunch it may be from a Cooper S. If it is, I hope to find the rest of the car hiding in my shed 
Am I right, S stuff? What ratio? Worth much? Thank You all for your help. Regards, Lindsay |

Yep 12G1222 are Cooper S forged rockers. They are stronger than the rest but have poorer lift. When I checked their valve lift with an RE13 cam and 1275 head I only got 1.16:1. Sintered A+ ones were 1.18:1. Pressed steel 850-998-1098 ones were 1.21:1. All checked on the same cam lobe and head. |
