This is a good Forum. Each and every person should build the truck he or she wants and we should respect his decision.
If you watched the video about the Mercury he built the baddest Merc around but missed the details. The point “ Don’t drive it if it’s not safe” throttle sticking at 2200 rpm’s and questionable brakes. Which brings me to my point, the chassis. It is the heart and soul of your ride. Are you willing to trust you life and the lives of the people around you to questionable welds or brakes that cannot handle the horsepower. Do your homework. Make the truck what you want. A hot rod is a hot rod. No rule other than be safe. If you don’t feel qualified to do the work find a qualified person to do it for you.
One of the first things you need to determine how you are going to use the truck. Do you want a street truck or a show truck to take shows? That Merc was a show car. No way he could drive it daily. Blower sticking up thru the hood and I’m huge tires out back. Then plan your truck and stick to your plan. There is room for all of us. Whether you build a restored truck, a restomod, hot rod or show all require a strong foundation. BE SAFE.
