  1. 1986 Pontiac Fiero, along with the 6 speed transmission from the 06 Pontiac G6.
  2. I stumbled across this forum while searching for some other related info and found this thread. Thought you might be interested in a few pitures of what I did with one of these motors based on the discussion. There are a few others in the Gallery.
  3. From the album: 3900

    The 3900 crankshaft is made of forged steel and has 2.25" crank pins. I had the crank offset ground to a 3.555" stroke for a rounded 4.2L

  9. From the album: 3900

    The connecting rod had to be narrowed. The 3500 non VVT and 3500/3900 VVT motors all share a 2.250 crank pin diameter instead of the previous 2.00.
