Definitely a home or private build
When you say "have some fun with it" what do you mean???
If you plan to make some passes, the first thing would be before investing time and money would be to get NHRA to look at it to get tubing dia. and wall thickness, It will not pass spec as is , all you want to know is what you have and then go from there. Other than Eagle Field which is a no-prep asphalt surface. that rear end will not hold up to a heavy blown engine, compound tires, concrete & VHT. and stock axles and drum brakes are really not the best.
If the goal is to strip it down and restore it towards the era it was entended for, show it at car shows and cackle events, then by all means go for it as is and enjoy.
