But Dave is pretty easy going, doesn't mind hearing ideas.
It is my opinion that a realistic budget needs to be in place. Your build plan is basically defined by your budget.
I prioritize, what's most important, what NEEDS work vs what is OK but could use improvement.
This truck will get the most bang for the buck. And its not going to be a lot of bucks.
I think I have a form for "change orders" I could share with your oldest boy child....he could add the number of hours of work he will put in for you in exchange for you financing a motor like stxhunter has posted pics of. We already know its going to look great when it rolls out the shop door.
Have fun with the project, I did something similar with my dad and it was some of the best times we ever had.
