Joe22- There are GM V6's & even V8's that will bolt up to your 1998+ rodeo trannys. Check this link: http://myweb.cableone.net/bcanderson/trooper/AuroraSwap.html, This IMHO, would be more work than it's worth for a daily driver truck. You'd have to swap electrical, computer systems, cooling system, etc..etc. Keep checking the WWW & you'll find a good direct fit 3.2L DOHC. By the way, how did your engine die??
