First, I am sorry if this has been previously discussed, I have done numerous searches and can't find exactly what I'm looking for. So, what is the best way to achieve my final goal and what should I expect to pay for the components and to have it installed. I want to end up with a 350 engine, th350 or th400 tranny, np203 mated to my 4 spd transfer case. I know I will need to purchase the AA install kit, but in addition... Should I buy a used rig and yank out the components if so which one? Should I go to a wrecking yard and plan on rebuilding what I get? Should I buy factory new or reman of each? I have access to '79 chevy 3/4 ton pickup with a fairly fresh reman 350 engine (5K miles), th400 trans and np203 t'case. The guy wants 2000 for the rig is this too much?
