gettin my 68 caprice together..

I have a 1968 Chevy caprice 396 that I purchased about 6 mos. ago. Already I have changed over to 8mm wires, MSD distributor/plugs, and a flowmaster duals, oh yeah some 22" rims:grinyes: . I was wondering how much of an impact changing the intake will have. I really want to get her stronger. What are some other engine bolt on mods that will increase power? I know alot of people seem to be askin this but my car is alot older than most, do the same principles apply? Great site!!!

Thanks in advance, Fatboyhttp://i223.photobucket.com/albums/dd253/fatboygixxer/IMG00002.jpghttp://i223.photobucket.com/albums/dd253/fatboygixxer/onchrome.jpghttp://i223.photobucket.com/albums/dd253/fatboygixxer/IMG00001.jpghttp://i223.photobucket.com/albums/dd253/fatboygixxer/ChrissCameraPics007resized.jpg

Any engine is like a big air pump. The easier the air can flow, the more power you'll get out of it. So yes, basically it's all the same concept whether it's a little four banger, or a monster twelve cylinder engine in a nutshell, they all need to breathe.
