how much fuel pressure do you guys run on your camden setups?
im running 6psi right now but i think it is way too much..
plus i the richness of the fuel in the exhaust starts to get into the cabin causing my eyes to burn

 

Fuel pressure depends on the carb.

 

what would you recommend for a holley 390 nascar carb?

 

You should be pretty close. Try 4-5 PSI and see if that helps. I've never actually dealt with a Holley, though. Someone else should be able to give you a better answer.

 

5psi made my holley happy while I had that POS.

 

well something stranged happen before it was at 6 psi now its at 2-3 psi?? strange i didnt even adjust it either.

 

Your car needs this no doubt, VERY accurate. http://mrcmfg.com/catalog/product_in...roducts_id=163
