Got an 83 Ram Charger with a 440 today!

Here is the block area where the pump should mount. Do all the big blocks use the same pumps? If so I will try and find one out at the local wrech-a-part. I've also included 4 shots of the carb/intake. When the truck is started it idles very high and will not kick down. Takes a lot of pumping of the peddle to gt started, especialy when cold. While in gear it surges and only runs half decent when your in the throttle.
