My dad's got a 39 Century we're trying to get to run right, and we've noticed a few oddities in the engine. THe carb and fan/pulley/whatever you want to call it assemblyi are from a '48 motor. Got the engine number off it, so could one of y'all nice folks tell me what year this number's from: 6-3454490. Thanks

According to the info at Buicks.net, the engine is a 1938 model. Here's the link:
