That sounds like a nice set up for your nova . I think that a good cam for your set up is . Comp cams Xtreme energy #CS XE274H-10 IT IS 230/236 AT .050 AND 487/490 LIFT . This cam is big enough . For the intake go with the Weiand stealth air strike #8501 its a high RPM dual plane intake that makes big power . Try the 750 V/S Holley you have for now . I do think a 750D/P Holley will work better . COOL
