super charger would be cheaper than an H/C/I because with the heads comes new bolts, gaskets, pushrods (depending on size) Roller rockers, (head bolt bucshings in some apps) i spent over 1500 on just my heads and all the new stuff to put them on, plust the 200 dollar cam, and the 400 dollar intake which i belive w/ all taxes puts you a tad over 2000, and a novi 1000 super charger i belive is about 1800 bucks and you can even find a used one for like 1200 or 1500 if you look hard enough, and i beleivea its easier to install a supercharger than it is to swap H/C/I because you gotta take the whole front of the motor apart to get to the cam..... GOOD LUCK tryna get 75 horse power practically free, just bite the bullet and save up like the rest of us who swore we wouldn't until we just got a little too hungry for power, and spend around 2K (and thats if you do all the work yourself, no labor costs involved LOL) cuz unless u do NOS, which will be cheaper than 1000 bucks ( I beleive, didn't do much research on nos) ur not getting 300 horses. I'm doing a SHHHIT LOAD of work to my car, including heads cam and intake, and i'm not even gonna break 300 when its all said and done, i'll be lucky to break 290 lol GOOD LUCK my man.... come to grips with reality, it took me a few months to realize i wanted to go faster, and that it was gonna cost me....
