I'm building up a 306 sb for my car. I know I will need heads, intake, headers, cam, lifters, push rods, rocker arms, oil pump, oil pump pickup and drive shaft, oil pan, bolts and gaskets, timeing chain and cover, water pump. I'm trying to get as many parts as I can on a budget so I dont have to do too much when I swap the engins out. Are there any parts i'm forgetting?
