Should I trade?

It's a nice truck, and it will be fast. If you trade, you should drive it straight home and put disc brakes on it. Be advised that it will be VERY squirrely on top end if you run it at a 1/4 mile dragstrip. A friend of mine had one set up pretty much the same way, but had a 500" stroker in it. It was in the 10's, and looked very impressive carrying the front wheels 50 or 60 feet off the line....but it wanted to lift the front end when you got it over 120-125 mph. He sold it so he wouldn't get killed in it! Good luck.
