So... I called an older Dodge dealer and had them run the vin.... They said it was a 360 built in Missouri with federal emissions, and a 6-10,000 GVW and it came with a holley 2BBl. he gave me factory 2 carb #s to choose from... R8925A and R9816A. I crawled under the van and had a look at the block #s and it still is the original 360. so I went to my local bumper to bumper and they said I now had two choices, and only one is available... lol .... United reman # 6-6264.... It will be in later today, and I can take a look.... It should be way closer than what's on there...
