Center squirter pump cams

[TheNovaMan]

Here are a couple not-as-good pics of mine:





Here's what I've managed to dope out from catalogs and the internet. Holley doesn't have separate part numbers for their pump cams, except for the yellow and white ones for 4500s. However, Quick Fuel numbers and sells cams individually, and I think their parts are actually Holley parts in many cases. They have a brown cam that looks like it has the same profile as mine, but has only one screw hole. Its part number is 41-664 (remember that 664 is embossed on my cams), and it seems to be a brown cam for QFX/4500 carbs that's extra wide "to provide better pump arm engagement." So I think what I have is the brown cam profile, just with a wider lobe. Here's Quick Fuel's page on it: http://www.quickfueltechnology.com/accel...4500-style.html
