Ditto on the Holly/Weber from Langdon's. I bought an AutoZone rebuilt Rochester...$109. opened the blister packed carb in the store, only to discover the choke circuit had been incorrectly installed. The manual choke would not even close. I took this as a "sign". Bought Tom's H/Weber setup. Out-of-the-box it was great...the truck runs, and idles like a swiss watch. Tom's setup was a few dollars more...you'll probably want to spring the $12. for the water choke heat to 12 v electric conversion. I would highly recommend his setup if you are interested in improved drivability. I've got pics of the carb and linkage setup in my webshots "shoebox". Hope this helps.
