Hey Boys,

I´ve seen a lot of different Four engines over the years… all types beginning from K0 till F2.
I´m always wondering about the different Cam stamps. Atm I´m rebuilding an F1 engine. It´s cam is marked with “R2”.

Is there any list available what this markings are telling? Which model has what cam?

Regards,
Bergi

even 500/550 cams have r2 on them.

I´m talking of 750 cams...
I´ve already found some answers here in the forum.
looks like nobody has a list

i realise that but im just saying the r2 mark doesent just appear on 750 cams,which are entirely different,the 500/550 all have the same cam,the 750s used a few different ones through the years as you know.

 I believe the consensus around here is that the "R" number stamped on the cam is more of a mold number and not anything related to its specs.

There is NO marked way to ID a Honda brand cam
