My '68 H/O had a service engine in it. Appeared to have been relatively low mileage before someone pulled the intake off and let it sit for 20+ years, effectively trashing it...

Pulled the cam out of it last night, and am trying to figure out what it is. It should be a 402194 (308*), but you never know what shortblock was put in. The distributor is a 1111289, so it's an A/C distributor, and my car is non-A/C. The engine did have D heads.

Attached are some pictures. On the distributor/back end of the cam, there is an '02' ink stamp and what appears to be a '195' stamp, though it's hard to see.

I don't have a '68 PIM engine internals section, but I do have a copy of the '69 PIM engine section (picture attached, you'll have to open the picture in a new browser window and zoom in to read it). The 402194 cam assembly had a cam part number of 402195, but per the PIM should have been stamped '194'.

Is it possible that the factory was stamping the 308* cam '195' at one time? I don't see any other cam number that ends in '195' in factory literature, but I may have missed something. There was a '165' cam, but then they would have stamped the '9' upside down (and PIM doesn't say the far end is stamped).

And before someone asks... no, I'm not planning to try re-using it.

Can you go by chamfers and notches on the front end, per CSM?

Good question... attached is a picture of the cam nose and the '68 CSM. It appears that it would be the 287/285 or 286/286 using just the front view.

I guess what's not clear from the PIM or CSM is if the 308 and 328 cams used the same nose chamfers/notches and had numbers stamped in the back as well? The small holes on this one are at 3:00 and 9:00 positions, the CSM/PIM show them at 12:00/6:00.

I'm pretty sure you have the 308-degree cam. I can't see any other reason to stamp "195" on the end unless it's the 402195 cam and 402194 assembly. That's too big a coincidence.

Note that in the manual the end they stamp is the "rear end view," not the front view with notches as for the other cams. The 402194 and 400165 cams were both ground from the exact same casting, 389410. You will find that casting number in the rough sections between the lobes, one digit at a time.

As final confirmation, shine a very bright light on the cam and clean it as needed. You will probably find the paint stripes, again on the rough casting areas. One white stripe is a 402194; two white stripes is a 400165. Let us know what you find.

Luke, still have the original 400165 out of my 68 W-46 - will look at it tonight for what marks it has.

Luke, just looked at the original 400165 cams out of both the Hurst and the 70 W-30 - neither has the 195 stamped in the back, so I'm pretty sure yours IS NOT a 400165.

Thanks Brian and Joe! Really appreciate your help. I'll try cleaning the end and watching for paint stripes to appear. The engine got a lot of moisture in it from having no intake, so a lot of light surface corrosion is present as well.

The paint stripes aren't on the end, they're on the rough, as-cast areas between the lobes.

Crap! Sorry for misreading that earlier, thanks for the correction. I went back out and looked tonight, and it's not obvious... I'll work on cleaning it this weekend.

83hurstguy

Spent more time than I should have cleaning, and nothing is showing up in terms of stripes. Oh well. I'll put it in the basement for future reference.

Thanks again for the help, guys.
