Re: 8cm cam grind
The 1CM cam came about for the change over to the rotator type valves and the automatic transmission.

Re: 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.

Re: 8cm cam grind

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.

Re: 8cm cam grind
Do you have some specs to compare the cams?

Re: 8cm cam grind
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. Terry

Re: 8cm cam grind
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
