HOLLEY Question

[Ranz1]

Were is a good starting point to set my "pump cam" for the Primary and Secondary? It is a 600cfm #4776 type:4150 for a 460 BBF..................I wonder who is going the be the first to tell me to get a 750cfm smile_sp

I won't tell you to get a 750....get an 850, they work better than the 750 :D As to the pump cam, are you referring to the position setting or the cam itself? Most Holleys are set in the no. 1 position depending on what cam you have. Check color as they are color coded and check both pri. and sec. They can be different and usually are.

For most applications a 330 Pink cam in the number 1/1 position will work. Your best bet is to ditch the 650 for a 750 or 850DP.
Most Marine applications work best with a 50cc secondary pump (brown cam number 1/1 position) and a 30cc primary (330 pink cam) with a slip linkage.
To answer your question at hand, set it up in the number one position.
Hope that helps.

Thanks 058 and Hotcrusader76.
Hotcrusader76, I dont know if you remember but i asked you for help about 4 months ago when i was taking the carb apart. Well FINALLY got back to it. It cleaned up nicely. A friend glass bead blasted it and got rid of that ugly yellow look. It now looks like clean aluminum :) . If i need any more help i'll post. Thanks, Anthony
