350 2bbl Build-up

Short answer: The “best” build depends on your goals (match all the components to them), but for a normal streetable 350 the short version is:

  • Intake: a 1967–72 4-bbl intake
  • Carb: Quadrajet
  • Cam: around .450″ lift; consensus is no more than 214/224 duration at .050″
  • Heads: if virgin, you can mill up to .060″ (removes about 12 cc from the chambers)

A good order of operations: set general goals, then tune what you have (cheap gains), then address gearing, tires, and transmission/converter, and then the engine. For the full discussion, read Jim Hand’s articles and search the Q&A archives at classicalpontiac.com.
