Hi Ed, Bill, and jimgmc,
Appreciate the feedback. My truck is a 1949 GMC FC102. I confirmed its a 228 as I have that stamped just aft of the distributor. The head part number is stamped 2136477.
As I read the chart from jimgmc it appears to me the correct intake from the factory is the 6107377 for my FC102 truck, which was installed. The one I purchased from eBay is a 2194002 which is applicable to the 100-22, 150-22, etc., or non FC.
Am I reading that correctly? Thank you.
