Keep it simple and use the 066 cam, used in the '68 320 HP 350 HO auto trans applications.

Here's the perfect time to clear this up.

I assume that the Melling SPC-4 is an 066 clone, and that the Melling SPC-5 is an 067 clone. If this is NOT the case, will somebody please post the correct info.

Also, please list all brands & part numbers for 066 & 067 clones, and links to this info.

Thanks !

Butler shows some specs for the SPC-5, but don't say what it's a clone for.

This list on the Wallace site shows some specs for factory cams.

Here's some more specs. As always, not all online info agrees.

Paul Spotts says this cam is "...factory blue printed 9779067 - 066...". Don't see how that can be possible in one cam, since the two are SLIGHTLY different.

Also says "...Made by same company that supplies Melling, and others - US made!..." So, I assume it is exactly the same cam as either the SPC-4 or SPC-5.

Here are the Melling specs. Pontiac cams are near the bottom of the page. SPC-4 & SPC-5 are similar, but different.
