Miles Posted August 22, 2010 Share Posted August 22, 2010 I just installed a Holley 570 Avenger on my 350 SBC in my 240Z. The exhaust pops at idle and cruise. Has a little sag just before the secondaries kick in. Off idle response is good. Quote Link to comment Share on other sites More sharing options...
