Im thinkin about pickin up a stock throttle body like this one http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2457457613&category=33558 And having it ported and bigger butterflys put in..IS this worth the time and the money?? has anyone ever done this?? One of my buddies did a single blade on his vette and he gained alot of power. Also how much would it cost to have one ported.
