When the bolt fell out and clinked its way down into the engine bay without making the welcome sound of hitting the pavement below, I stepped back and asked myself, “Why?” Not why had the bolt fallen out — I already knew that. What I wanted to know was, why do I keep doing this? Why do I keep willingly spending my free time working on old cars only to wind up aggravated? Hadn’t I learned anything in the 30-plus years I’ve been at this? I could be sitting on the couch right now, instead of crawling around on my driveway trying to find that damn bolt. I stood there for a few minutes, reflecting on all the time I’d spent rolling around on that piece of pavement over the…

CHALLENGER AND BARRACUDA POWERTRAIN DATABOOK: 1970-2021 LIGHTNING PRESS • AMAZON.COM • $24.95 In the 1970s, and starting again in the 2000s, Plymouth and Dodge offered buyers an incredible range of factory-installed engines, transmissions, differentials, and axles that allowed enthusiasts to tailor their Barracudas, ’Cudas, and Challengers to every purpose and performance level.

FIRST THINGS FIRST Q:I am 63 years old and semi-retired. One of the items on my bucket list was to rebuild a Chevy 350 engine, but the traditional small-block has fallen out of style, so I have set my sights on an LS engine instead. Here is my question: In your opinion, what is the best LS engine to rebuild and tune to meet my bucket list? I don’t want to go crazy with the build, maybe 450 hp. Can you also give me a ballpark cost figure, as well as what would be a good automatic transmission to use with it? Thanks for your help. Ray Heberling Myerstown, Pennsylvania A:I will begin by commending you for the desire to accomplish a long-time goal. There are a number of questions…

When I purchased my first muscle car, I simply left it as delivered and enjoyed it with only a few minor appearance changes. Some of my more affluent friends added new tires and mag wheels, upgraded sound systems, different steering wheels, and more. That was beyond my means at the time. This GTO is a totally dependable driving classic that I don’t have to worry about when I want to take it out to a show, or just a nice weekend drive. All the revisions I’ve made are (or appear as) factory original. Another factory part that was a little hotter or flashier might not have been on the build sheet, but it could have been, so why the heck not?…

FATTER CHEVELLE RADIATOR Q:I own a 1967 Chevrolet Chevelle Super Sport that will overheat in the summer in stop-and-go traffic. I was told at a car show that I had a radiator for a Chevy small-block (2-inches wide) instead of a bigger one made for the big-block like the 396 that I have. I found one in a supplier catalog for the big-block but they are back ordered. I cannot find a replacement unit with other suppliers unless it is an aluminum one, which I really don’t want —I would like to have the original look. Any ideas where I could find one to buy in the next month or two?

In most areas today, gone are the lif›s, mechanics, attendants, and full-service gas stations. Where have all the service stations gone? For you younger readers, there was a time in America when there was such a thing as a service station. There, they pumped your gas while you sat in the car; they also checked your oil, washed your windows, repaired your vehicle, and actually smiled while doing it, regardless of the weather. Hard to believe, isn’t it? Station “attendants,” as they were called, also wore uniforms with the logo of the brand of gasoline sold embroidered on the shirt, and a military-style hat. I hate to admit this, but I remember when high-test or ethyl 102-octane gas was 26 cents per gallon. My original ’65 GTO loved that gas…
