I was thinking about purchasing a Holley 500cfm 2-barrel for my 360 because it has a 2-barrel intake, or would it be better to buy a 4-barrel intake from the junkyard and put a double-pumper on it. I was thinking about putting a hotter cam in it but heard i would need new rocker arms or something. Just wondering, any info would be appreciated.

I'm interested to see peoples responses here because i'm looking at getting a performer manifold/4bbl carby and bigger cam for my 390.

But at this stage i'm in the same boat as you.... not sure what's the best way to go!

In my educational background experience, I have an Associate's Degree in Automotive Technology, if you have a "High Mileage" engine and are contemplating upgrading the camshaft to a higher performance one, you can eventually cause bottom end stress which in turn can cause your piston rings to wear faster causing loss of compression as well as oil consumption. I dont know if you are referring to a lower mileage one but maybe this is good info for you. As for your fuel delivery question, I personally would go with the 4bbl intake and carb, depending on how hot the cam you want to use is, I would recommend a 700cfm carb. Your choice of brand though. This should let your big block breathe a little better as well as shaving a few pounds off your engine by using an aftermarket aluminum intake, unless of course you have access to a stock one.
