300 HP out of a 318, is it possible with bolt ons?

It takes a lot of reworking and customizing of parts to get 300HP from a 318.
It's no longer a 318 if it's been bored or stroked.
a stock (early) 318 makes 230 HP so i don't think there's a lot of "reworking & customizing" in the parts department to find 70 ponies.

stroked, sure. no argument there. but a 30 over 318 is still a 318.
