Hello Folks,
I just purchased a 1955 Willys Station Wagon for restoration. It has a Chevy I-6 235 sitting in it. For 40 years this rig sat, should I pull it apart and replace gaskets? It was never started after being bored.20 over and dropped in the wagon.

Can I tune or change parts to get better mileage from this I-6 engine? Does anyone have any experience with these older engines and either building them up or improving serviceability? I do all other work on my restoration projects except engine math!
Thanks
Van
