i have a 93 v6 5 speed pickup i also have a 93 buick century with a 3.3 v6 ( same 90 block as 3.8 only different stroke length) i understand that these moters have a different belhousing (smaller it appears) than the more common smallblocks 4.3 v6s and rwd 3.8. Ive seen a few post on here on this subject but everyone just sugest the more powerfull and simpler 4.3 swap. But im not looking for the extra wieght of power just better low end torque and gas millage. I can probably figure out the wiring and build the motor mounts but have no were to find a bellhousing adapter or a gm automatic that can be adapted to my transfercase any help and information would be greatly apreciated thanks!

 

I'm not all that familliar with Buick engines, but cant you hook a turbo 350/400 or a 700R4 to it? If so, then you can use an advance adapters adapter

Contact Downey Off Road and ask them the question, or Advanced Adapters. Both of them are very helpful and very knowledgeable. I have a RWD Buick 231, TH350 with AA adapter to Toyota transfer case. I have about $2000.00 into the conversation (motor,trans,adapter,custom radiator, holly truck avenger carb,motor mounts). Check Craig's list for RWD V6's I believe that they would be an easier conversation.

 

hmm.......?


bahha

 

Get a turbo 350 that is what i used in my oringinal swap with the 225 buick but i lucked out and found a dual bolt pattern housing which is both buick and chevy

 

thanks for the help guys but im begining to see that its either gona be imposible or cost a lot more money than im willing to spend i think ill just gear my t case down so itll at least go through the woods a little better and just keep beating on my poor 3.0 for now plus i might be geting a cheap 64 buick 430 and th 400 for my 71 gmc so then id have a great runing 350 looking for a home =]
