my friend is sending me a holley 600 4 barrel, currently i am running a rochester 2 barrel, what parts to i need to convert this?

 

Well for starters you will need a 4-barrel intake, or a way to adapt the 4-barrel to the 2 barrel intake. You will probably require different linkage, fuel lines, and other hardware. What engine do you have?

 

you need a new intake if you want to see any benifit from the 4 barrel upgrade, you will need to reroute the fuel line, and most likely have to redo the throttle linkage, you will have to make sure you have your vaccum advance hooked up right, lots of holleys have special ports for the distributor, but knowing the engine would help LOL
