Okay, we weren’t quite that naive about what we read regarding upgrading to 1.6 rockers on our small-block Chevy for the first time, but it was close.
The engine in question was a decent runner with 30,000 miles on the mild-performance rebuild. The rebuilt engine was purchased used, and among its selling points were 0.030-over 9.5:1 pistons, moly rings, 1.5 roller rockers, a Performer RPM intake and a brand-new Holley 750cfm carburetor. The cam wasn’t a perfect match to the torque converter used in the previous installation nor was the final-drive gear ratio. As a result, the owner planned on stepping down on the cam chart to a Comp 286H-10 cam, which came with the engine in its original box. Also included were a brand-new factory Z28 oil pan and a factory timing chain cover to replace the cheap chrome pieces. For $300, the engine package was a deal, and one we couldn’t pass up. We sold the aforementioned chrome pieces and matching valve covers for $50, getting us the engine at the bargain price of $250, and we still had the new cam and lifters on our shelf.

Now that the typical Chevy buildup cars (Novas, Camaros, El Caminos, Chevelles and so forth) are well over 30 years old, most have had several owners and lots of abuse. One important yet often overlooked area during a car’s lifetime is its locks, and by now, most early Chevys have mismatched or missing keys. Some don’t even have any keys or locks when you buy them. If you do find a car that still has its original keys, it is very unusual.
What makes more power: carburetors or computers? While the ultimate answer is that a sophisticated electronic fuel-injection system will virtually always outpower a carburetor, the real question may be whether the power gains are worth the extra expense and complexity of installing an EFI system.
You can’t throw a stone these days without hitting an aftermarket aluminum cylinder head. They perform as good or better than anything the factories put out, and then some. They are much lighter than iron heads, and they’re now extremely affordable. Thanks to competition in the aftermarket, it could easily be said that for the performance and price benefits of a new set of aluminum heads, why would anyone bother refurbishing a set of iron castings?
This is the problem in a nutshell: When we are traveling in an automobile, it may seem that we personally are not moving, only the car is. But that is not the case. If the vehicle that we are traveling in happens to stop suddenly, we won’t, unless … there is something there to stop us. That something could be a seatbelt—or it could be something less desirable.
The cold hard fact is that injuries can be suffered during an auto accident. Injuries such as those sustained by the face and head as a result of being thrown into the windshield or dash. Or it could mean those nasty abdominal injuries due to contact with the steering wheel. Either way, it doesn’t sound like much fun. They can also be prevented.
