8cm cam grind

That makes a lot of sense. The automatic transmission would seem to me to require a milder cam for a smoother idle to accommodate idling in gear when stopped. Maybe, maybe not.
 
May I ask if there is a (best) stock cam for the pre 8ba style motors with the front mount dizzy?

Just out of curiosity, does anyone know if there are "1CM" ('51 Mercury) or "EAC" ('52-'53 Mercury) separate grinds?

I dug through my cam charts and found that I did degree a couple 1CM cams and for all practical purposed they are identical to the 8CM.

In my opinion, yes; the 32-34 steel cam. In 1935 with the introduction of the bigger, heavier bodies, along with cast iron camshafts, Ford 'detuned' the cam timing.

8CM that I degreed when building the 260 Merc:


9* 53* 50* 7* (checked at .014/.015 lash)

.330 lift at 0 lash



Compares nicely to the 32-34 cam Brian posted above. I think it'd be nice with the front modified for the early engine. An EAB cam is also very close to these numbers when advanced 4 degrees.

Any ideas what lift these numbers were taken at?
 
You can install an 8ba style cam in an early block and front cover. Then you can run a late style distributor. W do this all the time
