HP 500 Cam and Blue Carb Specs??
 
Standard HP500 Blue Carb, what are the Jets, Power Valves etc. I am removing my supercharger and building the block back to HP 500 specs.

Any suggestion on Cam? What were the cam specs on the HP500's?

I would like to get as close to HP500 spec as possible with the cam so I can just use the Merc recommended jetting. Perhaps someone else has a cam a jetting spec that is tried and true?

Bob, Thanks for the info. I contacted you last week via phone and my engine builder should be in touch soon.

Holley 800cfm HP500 stock jetting is:

Primary - Port 81, Stbd 75
Secondary - Port 89, Stbd 93

6.5 PV in the front. The secondaries don't have a PV.

If I was rejetting, I would probably just use 77 primary jets and 91 secondary jets.
