I have a 1950 1/2 ton with 3.55 gears, saginaw 4 speed. and a stock 216 which runs real well. It was rebuild and mignt have insert bearings conversion. It was rebuilt by local norwegian rancher known for his mecanical abilities. The truck is mostly driven about 60 to 65 mph 27 miles into town and return. Would splitting the exhaust manifold, Fenton hearders, or Clifford headers be og advantage? I'm also concerned about cold weather starting and running. It was 26 degrees the other morning.
