I’ve had theses core since the early 80’s. The parts manager at my local Dodge dealer was a good friend and I walked in one day and just said, “ your parts are here” and proceeded to walk me over to a pile of parts that filed up my pickup bed for next to nothing. These cams cores were in the bunch. I have no idea what they are but since I’ve been looking for small block cores, I need to research these more. They are obviously unground roller blanks but I have no idea of the makeup of them. One of my buddies called it an Endarols blank after he saw it. Another told me it was cast iron cam and it should be a little harder than than a regular old flat tapped and should not need a bronze gear for the oil pump shaft. It’s has CWC cast on one end and 2118 E on the other. Anyone know?

Cast iron cores, not my choice for solid roller cams
Probably intended for solid or hydraulic flat tappet cams

suitable for many hydraulic roller grinds i think....to be able to use the stock intermediate gear is a plus in my opinion. Seems like full time oiling with the groove....one thing to consider. Ask Ken Heard / Oregon Cam Grinding if that fits what you need or if they can use these.

One of my buds that builds a lot of custom grind cams for his circle track motors, said they may be higher on the hardness scale since the were roller blanks. Idk

One of the things that bothers me about these cam cores is the width of the lobes. My stock Mopar SB lobes are right at .600”. These are about .500”. Bullet wants me to send them a core to look at so they figure out if it will work.

The narrower lobes wouldn't concern me too much, a flat tappet only runs on a small area of the lobe. But I'd still speak to my cam grinder obviously, they're the experts.

I’ve got several of these cores. I’ve got hemi roller cores just like this with the narrow lobe and one flat tappet hemi core with the wider lobes. I’ve got several old hemi roller cams that are ground and they are on a cast core just like this. I’m assuming this is what they used years ago before billet cams were made?
