Omega's77s30 Posted May 2, 2014 Share Posted May 2, 2014 Ok per instruction I'm starting my own thread. I have a 77 280 with an n42 block and p79 head. I drove the car daily before it was parked 7 years ago in DFW Texas. It has been shipped to my current home in southern Oregon and I am trying to get it to what it should be. I am currently going over the body and finding the usual rust spots and such to fix. Now that you know all that junk, here are my questions: 1. If I want to shave the n47 egr intake down to the basics ( crankcase vent, egr, brake booster vacuum, any I'm missing) and get rid of the AAC and cold start do I need to do any ECM tuning? Should I just get a non egr intake? 2. What negatives if any are there of an a/c delete? It never worked anyway... And I'm forgetting my 3rd question... It sits right now with the drivetrain out so I can deal with the rust and put new suspension bushings in, when it goes back together I hope to do a few minor upgrades( headers, aftermarket fuel rail, bigger radiator, e-fans.) thanks for any help given Quote Link to comment Share on other sites More sharing options...
BluDestiny Posted May 2, 2014 Share Posted May 2, 2014 Just get a non egr intake. Only vacuum ports you need are fpr, brake booster, BCCD, and PCV. There are no negatives to an AC delete. Mine never worked so I deleted everything in the bay for it. Quote Link to comment Share on other sites More sharing options...
Omega's77s30 Posted May 4, 2014 Author Share Posted May 4, 2014 Are you still using the air conditioner idler pulley for your water pump? Quote Link to comment Share on other sites More sharing options...
NewZed Posted May 4, 2014 Share Posted May 4, 2014 This is why you need to just start bolting things together. Then you'd know that the water pump doesn't use the AC idler. Quote Link to comment Share on other sites More sharing options...
