If you want to keep the original look a 235 upgrade would make sense and it is a lot better engine than the 216 splashers(purists save your responses you know I am right). They are also available usually in running condition for $200 around here. It always comes down to what you want to do with the truck, you are right sometimes the original route can be expensive and face it no matter what it is 60 year old technology in regards to braking, steering and performance.
