well guys i just bought what was said to be gsr cams the guy was not 100 % sure that they were but would give me a refund if they r not. i looked at pictures of cams and tried to identify them and didnt really have luck . the guy told me they came out of a 2000 gsr .the intake cam has 3 protruding rings and 1 engraved ring and an A . the exhaust cam also has the 3 protruding rings and 1 engraved ring and a C. like i said i did a search and i think i just got lost

 

measure the vtec lobes lift.... should be .426

 

i dont have th slightest idea as to how or what with to measure the lobe

A Vernier caliper will work. People often call this a dial caliper.

The cam lobe heights follow:
IN Primary: 1.3154
IN VTEC: 1.4322
IN Secondary: 1.3601
EX Primary: 1.3036
EX VTEC: 1.4063
EX Secondary: 1.3536

Of course, these are inches.

 

if ican get a hold of one ill check but does anybody know the visual specs like teh rings and such

 

you wont be able to tell by the visual specs.... a vanier calipre, a micrometer or a dial indicator will all work.... the lift on a cam lobe when using a micrometer or vanier calipre is measured by litering pinching from the peak of the lobe to the bottom of the lobe. using a dial indicator, you set the indicator on a flat surface over the cam thats on V blocks, then you place the pin of the indicator on the lobe to be meauserd, then turn the cam... the indicator will do the work for you, this tool along with the vanier calipre are the least accurate. the lift on the gsr vtec lobe is .426" no lobe i've ever heard of is over an inch.... so dogginator, i dont know where you got those from. a big cam lobe like they use in winston cup blocks is .720.... and ive never heard of much bigger than that.

You misread my post. The numbers I quoted are for the cam lobe heights, not the lift, as printed in the 1996 Acura Integra factory service manual. Measuring lift requires the cam to be mounted and is far too difficult for simple identification purposes.

BTW: What is a Winston Cup block?

sorry, brain fart, lobe itself is what dogginator said. you can measure acutal lift outside the head, you measure from top of the shaft to top of the lob.... you can also use the dial indicator to tell you.
