Can anyone provide me information on markings of rocket motorsports valvetrain and m23 cams. I got a type r head that is suppose to have the parts and just want to make sure since these are my first rm items. Pics will be useful otherwise just write down some descriptions. Thanks.

 

Don't know the markings for EF-1's. If the seller is insisting they are RM's and not EF-1's, you got hosed.

 

how can i tell if they're also ef's.

 

Email me some pics.

 

does anybody know any specs on these cams? As far as I know I was told by a person that the specs on these ef1 m23 are suppose to be similar to the jun 3 cams. .

 

looks like RM doesn't have the M23 specs/lift listed.

^ came out a little retarded.

 

Not listed because RM does not make M23's.

 

M23 FTW

 

yeah I know that m23 is discontinued, that's why I am trying to find the specs on them. I'm guessing they're in between the m22 and m24's hahaha. no put I am trying to find some info on the cams to see if I should run them for me build or sell them and get different ones.

 

Send them to Rocket and have em measured

 

I don't think RM ever made M23's. Not to my knowledge anyways. Funny thing is, when I worked for Rocket, I brought up the idea of an m23 cam to go in between the M22 and M24. At that point though, he already had a solution in the works. He put the M24 in that role instead.
