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 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
