how to increase horsepower

i'm looking at upgrading to an 03-04 Z370 and i was wondering what i would be able to do/buy to increase horsepower/holeshot and where possibly to get it at. i'm thinking of getting some studs too.

The older the better!!

I personally haven't done anything with the 370! But if you are going to be anywhere near North Central Ill. Let me know and I'll let you take my little 349 Ovation for a spin! On the smaller motors there really isn't much that can be done, but then again anything you add will be very noticable! What I mean is adding 5hp to a T Cat you wont really feel it (about 2.5%) Now add 5hp to that 370!It's like 15%!

Look at your engine as just an air pump! Air in and air out equals HP! Is there anything you can do to increase air flow into the engine? How about out?
