Doug, if I recall, you have to use the Diesel Trans with the engine, the gas trans is not the same. Don't quote me on this, though, you might post over at the ITOG board; there are a few diesel nuts there.
The 3.4 Goodwrench crate engine won't work without a lot of massaging to the Trooper bellhousing. The starter in the Trooper 2.8 V6 is located on the drivers side; the normal S-10 position is pssgr side. However, the Camaro/Firebird 3.4, '93-95, has enough meat on the left side boss to be able to template the starter mounting holes, and mount the starter in the normal Trooper position. Other than that, you just transfer over all the 2.8 stuff to the 3.4, and in it goes.
A lot of guys at the ITOG site have done this mod, and I plan on doing it to mine next year. Check out previous posts there; there's a search engine, if you did a query on "3.4" you'll find lots of info. Good Luck....ed
