I posted earlier requesting a picture of a 1CM "crankshaft" when I meant to say "camshaft".

Let me try this again, does anyone have picture of a 1CM camshaft?

Thank you.

Visually you will not see any difference from an EAB to a 1CM cam.

Thank you, I just want them for my files.

So far I have never seen a cam marked 1CM.

I have a Merc cam. It's been wrapped up for years. I'll look at it tomorrow.

IIRC the one in my jalopy had EAB cast right on the blank. Only one I've had though

Attached are pictures of two 8CM Merc cams I recently sold. Specs for the '49-'51 cams are .338"/.333" int./exh.

flatjack9 · 03-28-2023, 09:58 AM

I have 8CM, 8BA, EAB and EA cams.

Merc Cruzer · 03-28-2023, 10:23 AM

I have pictures of the 8BA and EAA that came out of the old block and the new block. When I assembled the new block, after the machine work was finished, I used 1CM cam, but lost the pictures of it when my computer crashed.

Thanks for looking. Still hoping someone out there, has one.

Here are 4 NOS 8RT cams off the the grinder yesterday. Returning as “Smiley” cams.

36coupe · 03-30-2023, 06:58 AM

What’s a smiley cam?
What is the prerequisite for regrinding a 59 AB cam.
I would like the specs of a late Mercury cam, or a bit better. Going in early block with a merc crank, basically stock.
I have a few prewar and 40s cams.
How does a reground cam affect the drive train? Do you need to have longer valves or are the adjustable lifters enough to adjust the valves?
And lastly, what does it cost?
Thanks

Yea buddy.

3twinridges · 03-30-2023, 04:33 PM

If you take a stock 8RT cam, and regrind it, wouldn’t you have lower lift than the stock 8RT? Or are the lobes built up prior to the regrind?

KiWinUS · 03-30-2023, 04:45 PM

No you have way more lift. Stock just over.300”L100 right at.370. Base circle is slightly smaller.
Lobes are not build up. This is a standard regrinding procedure
