I am dropping an HEI distributor in to day so I guess it's true that no matter how good they run there is always something else we want to do to them.
My plugs had been in for a very long time and I had a few minutes Thursday evening so I put in a set of Autolite 985's. The old plugs were all that nice brownish gray color and every one of them looked pretty much the same which is always a good thing. I set them at .035" and could tell a difference in the idle right away.
Yesterday I went up to Dahalonega to see Mom and other than when I made 2 interchanges, I20 to I285, and I285 to GA 400, from the time I got on I20 until the controlled access ended near Dawsonville I never shifted out of 5th gear. I kept my 4.2 roughly between 1500-2100 RPM and there are a lot of hills between here and there. Now coming back I did have to grab 4th about 2/3 of the way up Six Flags hill.
According to my GPS my moving average stayed within a couple of points either side of 65 and my max speed was 78 which is a personal record for me. I usually stay under 70 but I had a nice long stretch of new pavement that wouldn't beat the crap out of me and was shooting for 80 but wimped out when I thought I was going to loose the door tops.
I am going to make the same trip next weekend after I have the HEI and MC2150 installed. I am also going to take 0III0forlife
's advice and pull the shift boot to see if I have a clearance issue with 2, 4, and reverse due to the 2" body lift causing it to occasionally come out of 4th and reverse especially when it is cold. When I move to Mom's house I will have a really nice 3 sided shed where I can work on my baby out of the weather.
Well after all this rambling there is actually a question here. As it sits now my CTO has nothing connected to it and the EGR is just sitting there. Is there any advantage to re-connecting the EGR when I install the MC2150? The fuel vapor canister is still there but is no longer connected to the CTO.
