The Dodge Challenger Message Board

When I bought my Challenger in 2000 the previous owner didn't know much about the motor except that it was a 340. He said the camshaft was a "930 S"...and that's it. Anybody who know of that one? Lift/duration etc. It was definitely an upgrade from the original camshaft that I put in a few months later. Now I'm thinking of putting it back but I wanna know the specs of it. Anyone who knows how to identify it?

A 390 S is a Porsche 911 turbo I think?

Apart from that I have never heard of one.

I don't know why but a lot of the modified cars we get imported into Britain have cams that the previous owners seem very unsure of. Even when they claim they have fitted the cam themselves.

If the cam is out of the engine at the moment there should an id number stamped in one end.

I looked at it closer today and this is what i found:

At the end of the shaft it says "LUNAT" which of course must be Lunati. Also at the same end of the shaft is the following numbers/codes, very vague but I THINK this is what they say:

110
RL589
E20E

At the other end of the shaft it says 1136.
Anyone who might have a clue? Oh yeah, once again it's a hydraulic cam which was in my 340 when I bought it.

Well these are the current Lunati cams for that engine. Trouble is yours could be an old design not made any more. Obviously Holley have taken them over.
