1992 Dodge Dakota 5.2 Magnum advice

I would like to pick up a extra motor and fix it up as I go.... When it's ready drop it in the truck. Cam and head work etc... So if I can get a deal on a 5.9 I will just get it for the future and start on it as budget allows. So I am going with 4.10s and a converter now. The converter im looking at is 2800-3000 rpm stall so I believe i will get that one. Thanks again
