Pete, would the same positive improvement be the case if I were to use a 351C? I incidentally have a good one that ran great when pulled, but haven't had a good use for it since. Not sure you could get the GMC dealer to install a 351C as optional equipment in a 1960 1000 series truck or not - came out of a 1962 GMC 1000 series truck, and the dealer did replace the 305D that came in it from the factory with the bigger 351C at the time the truck was being bought, so might have been available in 60 too? Do you know?
