Buying Engine Parts for a 1966 Fargo P300 Parcel Delivery

On this vehicle, the engine covers the internals and hard parts that build compression and keep oil where it belongs — gaskets, bearings, camshafts, lifters, seals and timing components.

  • Confirm you have the 3.7L 225cid L6 engine — every part on this page is matched to it.
  • Read the notes on each row for position, trim and spec qualifiers before you order.
  • Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.
  • Cross-reference the manufacturer part number against your old part or a service-manual listing.

What should I replace at the same time?

Where labor overlaps, replace the seals and gaskets for anything you open up; a timing job should always include the tensioner and guides, not just the belt or chain.

What do the market flags (US, CA, MX) on each part mean?

They show the market for which the manufacturer published application data for that part — where the vehicle was first sold, not where the part was made. If your 1966 Fargo P300 Parcel Delivery was originally sold in the US, the safest choice is a part marked for the US market.

How do I make sure a part fits my 1966 Fargo P300 Parcel Delivery?

Every part on this page is matched to the 3.7L 225cid L6 engine. Then engine hard parts are unforgiving of guesswork — confirm the casting or engine code before ordering, because one model year can hide two different blocks. The notes column carries position and trim qualifiers where they apply.
