Basically anything FWD from 87-94 that has a V6, Quad4 (maybe only HO or better), or Turbo 2.0. However, the V6 ones are the ones that will bolt up to a 3400. The others do have some advantages if you want parts for more aggressive gears though. Somewhere during 1991 (limited production) and for 1992+, all the HO Quads had the 3.94 ratio. Some people want this, but for a 3400 unless you have some crazy tires you're just going to go up in smoke all the time. I can already break traction on GoodYear Eagle F1s from a roll with my basically stock 3400.

The 3.4 DOHC cars have a Getrag 284 which is a bit beefed up. But it's harder to service and uses a more expensive pull-type clutch.
