What to do with a 400

So I got this truck I was told it had a 440 in and when I got it and started really digging I discovered it's a 400. I've heard you can do a lot with a 400 and make a 451 stroker and such, only if you have deep pockets haha. I at the moment don't have the funds for a complete machine and rebuild for my duster. What could I do for a budget type build with this motor for now? I want to go fast and do burnouts basically right now. Down the road I like a street drag car but I can't afford a stroker build. What do you guys suggest. Should I look for a 440 or what?
