Found this in an older Holley book, and put it in a spread sheet.

Here's a pretty neat graph of the cams all stacked up. I guess they're all in position 1.

No, that brown #336 is a 4150 cam cuz I've got one here and it's 4150 shaft size. I've also got a brown #664 4150 cam that is not listed on either of these charts but it's identical to the #336?

These are also a VERY different profile from the regular 4150 cams? Maybe 50cc pump on a 4150 carb?? :-k

PDF file has to be converted to .jpeg some way before it can be listed as an IMG file here. You "might" be able to view that PDF full screen then take a screen shot to convert to .jpeg. Then you might have to also resize it before it will appear here. If you get a link to it then PM it to me and I'll put it in Ron's post since he was the one that found it.

nice find guys, i have the overlaid graph from years ago when someone posted it on the innovate forum but the one mark posted is going in that folder too!

The yellow+brown (its more like a dark red to me) cams are for 50cc pump kits on 4150. Ive had a hell of a time over the years trying to convince people there are more than just OOTB pink pump cams for a holley lol.

Never had any joy with the 50cc pump/cam on my street engines (sub 500hp stuff, <360cube), poisoned the oil real quick with too much pedal work on the street.
