Technical Engine Dynamics cam ?

I bought this cam at Jefferson this last weekend, and I can't find any info on it. I was told that it is a stock Mopar 340 stock grind, but I would like to know for sure. It is a Engine Dynamics cam S-644. I got it cheap enough so if it isn't what it's supposed to be, I am not out a lot. I would like to put it in my 1970 318 with a 6-pak intake.

 

I seem to recall that JC Whitney used to sell Engine Dynamics cams. This was around 1979. I had one in my truck.

Unfortunately the old JC W catalogs don't list the manufacturers part number. But someone might have an old catalog...

 

Boy, this is a new name by me and I have a heck of a bunch of old cam info.

Sorry, no help here..

More than likely it is a re-boxed Elgin Industries or Clevite cam..

This might be of help to some.......

Here you go from my cam spec stash!!!!!!!!!!!!!!!!!

Clevite Cams
CHEVROLET V8 262-265-267-283-302-305-307-327-350-400, 1957-94 --- These can be installed in the '55 and "56 engines by grinding a notch on the rear cam journal that is like 3/16" wide x 3/16" deep x 1/2" long.. Use a small angle grinder for this. And my -097 cam I had in my old junk301 was done this way before I got it.

pdq67, thanks for the info, but it is a Mopar 340 cam, and all I see in your list is Chevy, cam specs. I am going to keep looking.

 

Hi,

Found an eBay listing that shows an interchange listing to Sealed Power #CS-644 for this cam here.

The specs for this on the Federal Mogul website are here. Also found some specs on the Melling website for their #SPD-22 here. Look at page 10.

Looks to be quite a mild cam, with a good idle and in all probability a torque peak around 2200-2400RPM. Max compression about 9.5:1 I suspect as very low overlap, so should build plenty of cylinder pressure.

There's a pretty good chance this was actually made by Camshaft Machine Company, as they supply cores & finished cams to many different sources - including OE. You'll usually find the letter CMC cast between the lobes if that's the case.

Hope this helps.

 

Engine Dynamics was located in Grand Haven, MI and was a compe***or to Camshaft Machine in southern Michigan and Engine Power Components, also in Grand Haven. Engine Dynamics made OE cams, their own private label cams, private label cams for Sealed Power and other traditional aftermarket suppliers, high volume finished cams for many of the traditional high performance guys and also supplied semi-finished blanks to almost every high performance cam grinder. They went out of business about 8-10 years ago.

I worked there a couple times as a materials manager and also did sales with the high performance guys such as Isky, Sig Erson, Howards, Crower, etc. It was good times. I used to have a few catalogs but I'm not sure if I still do - I'll take a look.

Thanks for putting me right Charlie. I recalled CMC and now you've reminded me EPC!

Thanks Charlie and Sam, that is what I was looking for. Sounds like it would be a nice cam for my setup.
