Melling SPD-22 cam question

[moparmat2000]

I picked up a Melling SPD-22 camshaft from Rockauto. Box is labelled as such. However theres no markings stamped into the cam. Anybody buy a Melling SPD-22? Is it stamped as such? Its basically a 68 340 cam.

Thanks
Matt

stick or auto cam?

 

[moparmat2000]

It was listed as same PN for both

That cam is not 68 specific. It's the 340 auto cam......actually a tad smaller. It's Melling's version.

Here it is. Probably a decent grind.

I have a big block Wolverine cam which is the same grind as a Melling MTD-2 (and the same one Edelbrock sells as it's Performer Plus cam). It does have a number stamped into the end, but it does not correspond to any part number I can find. They are all made by a company outside of Detroit called CMC and sold under different brand names. I wondered about mine too, and I measured the lobe lift and it seemed to fit the specs.

Theres no marking as to what it is stamped on the end of the cam. Is this normal? When I opened the box I was expecting to find SPD-22 stamped on the end of the cam.

That would make too much sense.

Maybe an email to Melling might reveal an answer.

There is nothing stamped on the end of the camshaft

Contact the supplier and manufacturer. We can't help you it seems.

This was the stamped number on the rear end of my cam

Well, you can always measure the lift and compare to the specs...but to answer your question, no I have not seen an aftermarket camshaft that's unmarked. Not that that means a darn thing. lol

Camshaft Machine Corporation grinds all of those generic cams for Melling, Comp, Isky, Elgin etc. Too much work to stamp every number on all of those different brand cams.

Nowadays, most parts are etched by lasers with identifying numbers. It sounds like it must be an old school machine shop.

SPD-22 Melling Camshaft
No number markings on the cams.

Just the SPD-22 label on the Melling Box they come in, made in USA.

Red or Purple dot on the timing end behind the bearing, white or beige dot on the rear of the shaft by the distributor drive.
That's it.

I’m thinking out loud here (can you hear the rattling). The maker doesn't want to put a specific part number on it so it can be sold to different vendors.

I notice mine has red paint on one end and a yellow dot on the other.

 

[moparmat2000]

I will have to check mine.

^^^^^ Kind of like these 2 cams,
Enginetech 644, and
Melling SPD-22

Same grinds offered at Rockauto, different part numbers.
Same Cam

Looks just like the SPD-22 cams here, same color dots.

For what it's worth. 1 beige dot on distributor end. That's it. No other markings.

CMC makes the majority of OEM cams for every auto manufacturer in the US....big operation.
