2005 Mustang GT for around 15k
Buy a centrifugal supercharger kit for 3500
Buy a tune and a larger pulley for another couple hundred
There you go. 500hp (crank hp) reliably forever. Good luck making it hook up if you run out that 20k before you buy tires
Nothing beats GM for cheap HP. The smallblocks are so cheap and plentiful, you can build a serious engine for a few thousand. that's all forged internals bored and stroked that makes 400-500 crank hp. and that's an NA engine. Take that 3k built motor and put nitrous or a supercharger on it for 1000-5000 and you could be pushing 1000hp.
I will admit the mustang is a better platform for one reason; it doesn't weigh as much as a truck.
I was shocked to see that Subaru cams were in the thousands of dollars, when you can get a cam for a GM smallblock for between $80-$400
