I have a 53 Chevy 3100 with the original 216 that runs but smokes and knocks. I would like to replace the 216 with a 235, I have collected 3 rebuildable 235 core engines and needadvice on which one to rebuild. 2 of the 235's are both 1955 first series truck engines. The third was pulled from a 59 belair car with powerglide. I ran it on a stand and it ran smoothly and quietly with the hydralic lifters but it smoked like a freight train. I am leaning toward rebuilding the 59 engine and using the adaptor to relocate the water pump. High performance is not what I want. I desire a stock , smooth running dependable driver. My two main questions I have are: I have heard that main bearings for the 55 first series 235's are rare and expensive and might be impossible to find in the future. Secondly, is a car engine with hydralic lifters easier to source parts for and good for a truck engine. Advice will be appreciated. George
