Just started Mk2 Cooper S rebuild.

Pistons are marked 060. What capacity is the motor?

Valves are marked RIC127 & REC120. What are the details on these?

Conrods AEG145. What do these come from?

REC120 - 35.6mm inlet
REC127 - 31.0mm exhaust
Paul Ivey (Race Engine Components) uses these numbers, not sure if anyone else does

AEG145 is the bearing cap number. I think the rod will be 521. Later Cooper S 1275. Early were 177s
