Gonna depend a lot on what you want done to the truck, do you just want it to run or does everything need to work correctly? If it's for the track so little things like the check engine light staying on won't be a big deal I'd say about 20hrs of labor (on the low side). Getting all the electrical gremlins worked out and the dash going correctly I would hazard a guess closer to 40 hours. These are just that, guesses, take'em for what they are worth.
