Hi my name is Jesse and i am new to the site. I just purchased a 1949 gmc 250 truck for restoration. This is my first restore. The truck has original 228 motor and turns free however I will be rebuilding it. I have most precision tools for measuring and checking journal dia. and brg. clearances and everything else but I am having trouble finding spec's and info on this motor. I would appreciate any advice or direction in this matter. I want to make sure it gets done right and would like to do it myself.
