It's pretty simple....

Any engine can be made to make big horsepower. The crux of it though, is that the larger the engine, the easier it is to make that horsepower at a lower rpm, with less compression, more streetability, etc.

For instance, I built a 445 inch Windsor that made 660 hp here on the dyno, at around 7000 rpm.

I also built a 529 inch BBF that made 740 hp, but it did it at only 6000 rpm, and had 700 lb-ft of torque to boot.

It all depends on how rowdy you want it to be, what type of gas you want to run, and what you want it to look like.

The BDR and SPF cars both will accept pretty much any engine you want to throw in them.
