Sure, any guy with a fat wallet could make 300 HP easy, it's as simple as dropping by the local speed shop. But what about the average joe who has bills to pay? This might require some theoretical engineering. I'm not talking about nitrous.
I believe it's as simple as reverting back to the old school. I think it's time to get out the text book from the late '70's and early '80's. So if any of you want to drop hints, advice, experience or knowledge, do it here. I will appreciate the help.
