Thread: Cam identification

Can anyone help me identify these cams?

They look like JWT cams , do the have SPORTCAM stamping ?

You wil have to measure the lobes to identify model. JWT has the cam specs on their site.

If I had to guess s3 or s4

Its a factory cam, one has a tan stripe on it. Take pictures of the colors on the cams, that is the best way to identify them. Not sure if the info is out there but someone might know what they are.

Need more info. Where did you get them. Did you pull them out of a running DE motor? And if so, was it a B13, B14 or what?

That stamped S looks like JWT, but that tan stripe is usually for OEM like squirlz said..

There's also some scoring on the lobes if u didn't notice

Both of my cams have paint on them. Looks more white than tan.

No s4 cams came with ANY paint of any kind?

What I'm talking about:

What in the.... whats with the crazy color on everything but the cams? is that oil deposits? ive never seen the inside of an SR20 look like that..

These are S4s? I had a question on some cams i had as i thought they were JWT. I called JWT and they said their cams do not have colors on them. This could have changed but that is what i was told.

Edit: The paint does not look as uniform as factory cams have on them, like the tan one above.

These have paint on them, so i retract my statements, they could be JWT cams, but again the paint is white, not tan.

Whip out a caliper and measure them up. That's as simple (and the least time consuming) a method IMHO

With that information, even if you do not know the original manufacturer, atleast you have a good starting point in your search, as now you know what specs to look for and try to match em up.

Who knows; KF could mean Kelford?? I have no clue............

I think I'm going to measure them over the weekend. I kinda always had my doubts about these. I'll report back what I find out.
