s30vise Posted June 2, 2009 Share Posted June 2, 2009 i have a 72 240z with a pair of SU's in it right now. Ive been having a lot of trouble with them so i was thinking about getting the intake manifold from AZC and putting a Holley 390CFM on it. Will this preform better then the SU' or is it going to be worst then the SU's. Just looking for some feed back. Thank you Quote Link to comment Share on other sites More sharing options...
