Slant 6 power?

i was just wondering how much power can i really pull out of a 225 slant 6 in my 72 demon... where can i find parts for it and how much is it going to run realistically....

What exactly do you want to do,a comfortable street car or a street terror?

A Super Six from what I have read will do real good,but there are some members here use a 390 1bbl Holley with a 4 bbl intake from several places some can be reasonable in prices to high in prices. Check ebay or the classifieds here.
