It is a know fact that more cubes equal more horsepower. Besides, physics drive everything related to making horsepower and torque.
Take the Chevy 502-crate engine. For $5500.00 to $6500.00 you get 502 or more reliable horsepower and a guarantee from GM.
To achieve that kind of horsepower from a small block you'll need to bore and stroke the combination and then in turn you must use the absolute best parts to make it work.
This has now caused you to spend the same amount of money or more to end up with a less reliable engine due to the greater level of modification.
I have been associated with 2 stroked motor build-ups. One was a 350 bored/stroked to 383 and makes about 536 horsepower. (Pulls a 3000lb 1967 Camaro down the quarter in 10.97 seconds)
The other was a 350 bored/stroked to 403 and dynos at 546 horsepower. This engine is approaching $10000.00 and is fairly reliable but very radical (Balanced/blueprinted and everything in between).
This combo is in a 1995 Z28 that is street driven as a sleeper. The car looks stock and has been insanely pushed to 194 mph.
