340 w/ edelbrock 750 need to know what jets to put in the carb.

My mildly built 360 with headers, 280H Comp cam and Weiand Stealth manifold runns excellent with an out of the box Edelbrock 1407 750cfm carb. All I did was move the pump shot arm down to the middle hole. Throttle response, performance and plugs are fine. I run a 1" 4 hole plastic spacer also. I'll be doing more tuning later but it's fine for now.

If you have a warmed over 340 with headers the Edelbrock 750 carb should be very close.
