The birth of the Mark IV 396 for public consumption occurred back in 1965. Its predecessor, the Mark I, started in 1961 on the drawing board, was finalized and built in late 1962, and was unveiled in race trim in 1963. It set the racing world on its collective ear at Daytona and other races, and then it disappeared, going back to Chevrolet Engineering for further development. Seeing that you could step up and possibly own the Marilyn Monroe of big-block engines, serious racers and enthusiasts had to sit on their hands for two full model years (1963 and 1964) before the son of this absolute powerhouse could be ordered.
Thirty-five years and $636 ago, we bought an 80,000-mile ’62 fuel-injected Corvette in Fresno, California. Sadly, the car had been stolen once. The fuel injection was gone as well as the T-10 four-speed transmission. A pair of bare 461-X heads was in the trunk. The engine was found to have a rocking rear cam bearing, which caused oil to shut off to the rocker arms at high rpm. At the time, the prognosis was that it could not be fixed, so the motor was replaced with a ’68 350hp 327. Since 1976, the car has been in storage, along with the original engine.
If you have spent any amount of time working on street machines, you are well aware that “bolt-on” parts do not always bolt right on. Still, it’s often a lot easier to modify those parts than to fabricate your own. The same holds true for such items as rollcages. Nobody pretends that a prefab cage is going to drop right into place without having to trim a single tube. That’s mainly because the economies of scale dictate that manufacturers make a single design fit as many cars as possible. Unfortunately, a cage that fits many cars probably fits no car perfectly.
Small-block water pumps are common replacement parts and are available at prices that are nearly impossible to beat. However, while getting a brand-new water pump for cheap is great, sometimes you need to keep the one you have. If it’s date-coded, or maybe you’ve installed a chrome steel or an aluminum water pump. You aren’t going to get those at the parts counter. In cases like these, rebuilding a water pump is preferred to buying a new one.
As 40-somethings ourselves, we know how it is to get, shall we say, tired and worn out. And when the owner of this ’64 Nova figured that age had done its worst to the steering system of his car, it was time to replace it.
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.
In the eyes of the Chevy enthusiast, ultimate acceleration reigns supreme. Everything plays second fiddle in the performance-oriented minds of many enthusiasts, including handling, comfort and so on—besides, those things are tough to quantify. Acceleration and top speed are what we are into and unfortunately, all too often, last on the performance priority list is braking. Remember, no matter how quick or fast a particular Chevy is, and no matter how well that Bow Tie handles, no matter how plush it is, no matter how straight the body panels are or how crafty it’s built, eventually you have to get the thing to stop.
Hundreds of thousands of these “little” big-blocks were sold in the 1960s. In 1965-66 alone, over 150,000 came in the Impala, Biscayne and Bel Air big cars. Few paid attention to them because the hot engine of the day was the L-78 with high-rpm, rectangle-port heads. But when stock eliminator drag racers began flogging the L-35, it responded magnificently.
