Hey guys...currently have a bone stock 305 TBI. has a bout 40k on the motor and im wondering where i can get a supercharger for it. I have emailed vortec,procharger and holley. Havent got an answer from any of them. Im lookin to stay smog legal. So any help will be greatly appreciated. Thanks guys.

 

Look into the weiand 144 series blower...from what they advertise should give up to 100 horses and remain streetable, you can retain the FI by buying a 670 cfm holley TBI, and the adapter plate to put it on a carb manifold. me personally i'd spend the 2K+ on good engine work if your looking to keep the 305. heads cam high flow intake manifold and a bigger tbi should give a decent power boost almost as much as the blower. now if you do all that engine work plus the blower...a 400 horse 305 is not impossible i believe.
