Claims of Project Buford T Justice’s demise have been greatly exaggerated, although I have not done a lot of quell them because of a lack of suitable update stories this summer, but the fact is that in the Spring I upgraded the car using an Atomic EFI kit from MSD and proceeded to drive the sucker all summer long. My schedule kept me away from the house a lot but when I was home, Buford got driven. It got taken to cruise nights, car shows, and just bombed around town with the boys in the back seat. High heat, rain, etc, the MSD Atomic EFI has fed the car reliably and accurately since the birds started chirping in the trees to let us know that warmer temps were on the way. Now that we’re sliding down the other side of that curve, I have a very accurate picture of what this system is, how this system works, and how it helped improve the performance of the car in both a fun to drive aspect and by far the fuel economy aspect. I installed the kit as most of you would, in my driveway. I wanted to do it this way because while I could have stuck it in a friend’s shop and made the whole situation a day-long affair, I felt that most guys would be tackling the job at home by themselves or with a buddy.
I am going to give you the blow by blow account of the install below. The whole job took me a day and a half. That was mainly because I didn’t do the “pre work” like having the bung welded in the header for the oxygen sensor ahead of time. I started the install with getting that stuff done. Had I done that, this was clearly a one day job. What you see below is how it really went. There’s no skipped steps or camera tricks, mainly because I am so bad at taking photos, the only trick I can perform is to actually get a photo to come out in clear focus.
While I didn’t plan on waiting this long to write the story, I did want to write it after I had gathered some really concrete impressions on driving the car. It is one thing to bolt this setup on, have the car start and report that all is well but it is another to get the system on and rack up a bunch of miles in sweltering heat and other conditions to see how it actually works. SPOILER ALERT: I have been very happy with the MSD Atomic EFI. It “self-learned” my car well even though the cam specs are on the outer edges of what they recommend, it has immeasurably increased the responsiveness of the motor, and it is delivered fuel economy gains of nearly 30% on the highway over the double pumper that was on the car before. Here’s how the whole thing came together.
