Anyone know what this cam is? This is EDB-E block with all the ECZ stampings on mains caps, crank, rods and pistons. Does it have specs like a '57 (256 duration, etc)? Or is a high rpm special cam for marine use? This marine interceptor engine also has auto-lite centrifugal advance only distributor with slot drive and special slot driveshaft to oil pump. I assume I can simply install a hex drive pump/distributor and shaft and put this engine in a car? Thanks.

Assuming the camshaft has ECK on it, it’s likely the 246° duration camshaft.  This cam will work just fine in a car application.  The ECZ on the main caps points you to a 312 but checking the bore size and stroke of the crankshaft will help to confirm this.  As long as the current distributor has fourteen teeth, then switching over the oil pump, drive, and distributor to the hex drive style will work.

Just be aware that other Ford cams were ground on the ECK core.  This is called out both in the B/P's and from actual cams that have been measured and verified. 

One may want to do some quick measurements, at least on the lobe lift to further identify if it is a 246, 256, or even a 260 duration.

I myself prefer marine cams, they make the cars into cruisers.
