I may have read the original question differently than others here, because he (IMO) was asking about "sales value of a restored/custom vehicle", and how to get the most money for it . Quality and detail will make or break any project vehicle, for sale or not . Unlike some who offered opinions here, many people would pay "top dollar" for a a good looking, reliable, mild custom truck, that they did not have a hand in building . Some would like all the "hard work done" and just buy and install their choice of wheels, and sounds . Hate to jump on the "trend wagon", but a used 6.0/4L60 will offer the best reliability and performance, for the time and money spent here . Then go into both axles with 3.55/3.73's for a REAL street and off road performer . Finish off with some "factory truck rally wheels" and reasonable 30" M/S tires, and NO MONSTER LIFT KIT . He is not asking about "building and then selling to another builder", he's asking about selling to a "buyer without a tool box" . I see it this way; "you can spend $5K for an off road flooding carb, or an on road continuous 700 R4 cable adjusting nightmare, or you could spend $7500 on a viable modern vehicle" .
