i agree jegs and summit are the bibles of highperformance
and the quadra junk is the best working carb you can bolt on that chevy
i run a 750q-jet and i love it
btw, do your self a favor and get rid of the stock camshaft while your under the hood, chevys stock cams are garbage, if youve got a 350, use a comp cams xtreme energy 262, heheh lost of good streetable power
