Note
Seems the stock base circle falls between 1.175-1.185.
Regrind cams seem to be in the 1.120 range.
The FFWD-DKS have the smallest base circle I have measured to date.

This is great. I was just wondering/hoping that someone already started a resource like this.

To all, please post the brand and model of the cams, followed by pics or describe the markings found on them. It would be extremely helpful to the community to have a single thread to go to, to help them identify their cams. I hope everyone will jump on the wagon and start posting. I'll upload my pics asap. I think I have Webcams.

You can add these to the top post if you want. These markings are on the cam gear side by the first cap.

Here are some photos of the Graveyard Motorsports 274 cams.
According to their site: 200 duration @ .050 .408 lift

Solid light green paint in the center of the cams.

Intake Cam:

No other clear markings on the exhaust side.

"GM 274" engraved behind the cam gears.
Now the intake cam had the red paint on it which leads me to believe this was another aftermarket cam size already because the previous engraved number was ground off.

You can see a tiny bit of the previous engraving on the right side of the dowel..
:hmm: Well, they are regrinds after all.

Been gonna do this for a while... Finally strapped the degree wheel to my shortblock, installed solid lifters, and measured the cams.

These were sold to me by Delta, as HKS 272 profile, all measurements taken with zero valve lash, installed with AEM TRUE TIMES ZEROED OUT. My block was decked .010", and the head .005".

They are .394" peak lift on intake, and .385" lift on exhaust.

Timing at .001" lift:
IVO: 25 BTDC
IVC: 67 ABDC 272* duration seat to seat

EVO: 72 BBDC
EVC: 24 ATDC 276* Duration seat to seat

Timing at .050" lift
IVO: 6 ATDC
IVC: 36 ABDC 210* duration @ .050" lift

EVO: 35 BBDC
EVC: 5 BTDC 210* duration at .050" lift

Also, I am running JE pistons pn 208478, at zero deck height, with a felpro gasket.

Piston to valve clearance:

Gears fully retarded: (-12*)
Intake: .220"
Exhaust: .070"

Gears zeroed out:
Intake: .150"
Exhaust: .170"

Gears Full Advanced: (12*)
Intake: .050"
Exhaust .250"


My old standard wiseco's have bigger valve reliefs.

This is 4-year old thread, but the info is still useful.

Anyway, here's an update on how to 'correctly' identify which stock cams you may have...

The letter IDs near the cam gears are not the correct cam IDs.

The workshop manual indicates that the cam ID letters are stamped on the rear of the cam, meaning the CAS side of the cam.

I just validated this as I have a set of cams embossed with 'G' on the cam gear side, but had 'F' on the CAS side of the cam.

Actual measurements of the 'G' cam validates it to be 'F" based on the list provided by mysticj @ 4g61t, and quoted by Dale above.

Here are the 'real' G cams from a Galant AMG...

Why do they make cam identification so difficult?! I've got these in my car and I'm pretty sure they aren't stock since it always sounded somewhat cammed. My Exhaust Cam is stamped with G and 4 dots, and the number "222" also stamped on the back of it, however it has a long number stamped on the actual rear of it and the letter "J" (seen in the pictures). My Intake Cam is stamped "H" with 6 dots, and 292" but has no other stamps on the shaft rear. Can anyone ID them?

INTAKE:
Base circle 1.185
Toe 1.378
Cam lift .193
Net lift .3280

EXHAUST:
Base circle 1.181
Toe 1.374
Cam lift .193
Net lift .3280

These came out of my 1997 Eclipse GSX. I didn't see anything in this thread or found any results from searching google. Anyone have any idea? Unsure if they are stock cams for this year model.

I Know this is an old thread, but i don't want to make a new post, so here are some specs off of a set of camshafts that came off of a "90 eagle summit 4 door sedan N/T 4g61 dohc, 5 speed manual.

Intake cam: ID marks by cas side [14] [9] and stamped [0]6] R3
Note: green paint on both camshafts.
Base circle. 1.183
Toe. 1.388
Cam lift. .205
Net lift. .3485

This is using bogusSVO math of 1.7×.205=.3485

Exhaust cam: ID marks on cam near cam side of block [1][2] [9]
[0][6] R4
Base circle. 1.184
Toe. 1.375
Cam lift. .191
Net lift. .3247
This is again using bogusSVO provided Math, in the link above on his post. 1.7×.191=.3247

We need a thread like this for 420a cams. There is actually a huge variation of cams that came in the N/T's and some of them are more aggressive than others. There were 2 different manufacturers also.
