Mysterious cam in a rebuilt cylinder I have here.

[andysbeta]

I have a freshly rebuilt 1983/84 LH2.0 B23F 160 head here with a slutted camshaft with the below inscription on it :

52573 , and stamped in ink P3. First digit/letter before 5 digit thingie is not legible.

What the hell is this? Some mega asteroid race cam? Or the most tame emissions cam ever devised?

 

[Wilford Brimley]

Mmmm slutted cam

 

[CEHepp]

I feel like I can clearly see a "K" on there.

 

[Wilford Brimley]

Looks like it says E and then the numbers

 

[vlvman]

Looks like a V to me.

 

[Wilford Brimley]

Actually almost looks like an L

 

[andysbeta]

I'm baffled, it almost looks like "T" but then I look at it again it morphs into whatever. A slutted L cam would be the bomb for the grandpa series drivers though.

I guess I can compare the lobes with a T cam I have tucked away in the shed and see if there is some radical or not so radical going on with this cam, aye.

 

[vlvman]

Got a photo of the lobes?

 

[TrickMick]

shoot a picture of the * LOBES *....

 

[andysbeta]

Will do that in a bit, need to get this thing out of the wrapper.

I did a quick flip over, and it is a SCP head, 160 casting? B23ft head then perhaps? What the **** is this thing I got here? It came in the trunk of a 244T I just bought.

measure the lift on the intake and exhaust lobes (difference between the total height and the middle width of the lobe)

Did Enem label their cams with a P designation a long time ago?

 

[sbabbs]

I have a small coolant passage 160 head from my old 84 B23FT motor. Do the exhaust valves have a dimple on them in the center? If so then they are sodium valves means it's a turbo head.

 

[andysbeta]

Yep, the exhaust valves have the dimple.

Looks like someone wanted to EFI this '83 244 perhaps, or who knows what.

that looks like an L-cam, except it's slotted.

shaft in question does not look *radical* to me at all..nice mild STREET CAM

Letter before the number looks like M to me.

 

[smokeyfan1000]

Lay a piece of paper over the unknown letter. Use a graphite pencil and lightly run it back & forth across area of letter the paper is covering.

Letter should show up more ledgibily on the paper.

 

[500dollar744ti]

did anyone else notice the dead insect in the slot area?

Was this cam a regrind because I don't see the grooves on the lobes. I have a M cam that was ground past the grooves on the lobes.
