Black_iss Posted March 25, 2016 Report Share Posted March 25, 2016 Can anyone walk me through on what I need to do slap some ls3 head on a lq9 and what came to put on it? Quote Link to comment Share on other sites More sharing options...
canadianVRss Posted March 26, 2016 Report Share Posted March 26, 2016 Things you'll need -your choice of rectangle port intake -4 bolt throttle body -X link for said 4 bolt throttle body -L92/LS3 heads -if you're a 03 you'll need to figure out a regulator set up if you go with a L92 intake -you'll need to route your PCV on the passenger side to your intake (I went pre throttle body) As for a cam, the LS3 heads flow great so let them do the work and not the cam. Low 220s intake and high 220s to low 230s exhaust is what I'd run for duration and somewhere around .600" lift. There's plenty of off the shelf cams that do well. Don't forget a stall for the cam and a tru cool Trans cooler for the Trans to keep the temps down, especially considering you're in Vegas. If I think of other stuff I'll add it. I'm sure I missed things. Quote Link to comment Share on other sites More sharing options...
