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

junkyardhero said
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.

Hard to gain 70 with bolt on parts.
