Towing

It is the nature of man to create circumstances in which he is compelled to pull a disproportionate amount of freight behind him. In a rapidly industrializing age, this phenomenon has multiplied to such an extent that many people now pull entire households behind them on a regular basis. Welcome to the world of mobile homes vehicle towing.

One can only guess what our cave-and-tree-dwelling forbears would have thought of these circumstances. The fact is, towing is a tricky operation at all times and under the best of circumstances. There are specific laws of physics that must be suspended for us to tow something many times our bodyweight behind us successfully. In that respect, it is a lot like flying.

In the modern world, there are innumerable situations that require towing. There are a mind-boggling number of automobiles on our roads today, and it is the nature of automobiles to break down occasionally. Constraints of space and budget force many to use trailer homes instead of the conventionally rooted house. Even those who believe in four firm walls need to shift homes every once in a while. And smooth functioning of any kind of industry requires an equally smooth flow of raw and finished products. In all these cases, towing is called for in some form or the other.

Considering what will be required of it, a towing vehicle will obviously need to have certain features that one is unlikely to find in one’s family sedan. For instance, it will have to be of sufficient dead weight and will require special brakes. One of the most basic rules of towing states is that a tow vehicle and hitch needs to handle at least fifteen percent of the total weight of the trailer (total weight of trailer plus contents). Not heeding such parameters is a sure-fire recipe for disaster.

The 1963-1967 Corvette Sting Ray

The second generation Corvette was the 1963-1967 Sting Ray, not to be confused with the third generation 1968-82 Stingray (1 word). The styling was the expression of many of the styling ideas of new GM styling chief Bill Mitchell. The interior implemented a dual cockpit similar to earlier Corvettes, but updated for the Sting Ray. Starting in 1963 the first hard top coupe was offered, featuring the a two piece rear window design. Bill Mitchell intended for it to form a visual connection with the central raised sections on the hood. The feature was dropped in 1964 because it limited rear visibility. However the 1963 Sting Ray coupe is now the most sought after model of second generation Corvettes.

Like all Corvettes, the Sting Ray’s body is constructed of fiberglass panels mounted on a steel ladder frame. Another new feature was the hidden twin pop-up headlights, which not only added style they aided in aerodynamic efficiency. Other styling cues of the Sting Ray include optional side mounted exhaust, a power bulge on the hood (this was wider for the Corvettes that had the big block engine), and absence of a trunk lid (access is from behind the seats). Additionally the Corvette’s convertible top folds away completely when not in use and is stored beneath a flush fitting fiberglass panel behind the driver. There was also an optional hard top. The different year model Sting Ray’s can often be differentiated by their side vent designs , for instance the 1967 had 5 side vents, the 1965 and 1966 models had triple side vents, the 1963-64 had horizontal double vents.

Sting Rays came in three engine sizes, the 327 cid, the 396 cid and the 427 cid. Horsepower varied between 250 and 435 hp. The 396 engine was only offered in 1965, and dropped in 1966 in favor of the 427. The 1967 L88 427 cid V8 marked the pinnacle of performance for the second generation Corvette. The V8 engines drive the rear wheels through a four-speed manual or a three speed automatic transmission. The Sting Ray also had an alloy clutch housing and alloy-cased gearbox to help with weight reduction and weight distribution. The 1963 Sting Ray was the first Corvette to have an independent suspension. The 1965 was the first to have 4 wheel disc brakes.

The 63 Corvette also had a racing option, the Z-06. The Z-06 was created by Zora Arkus-Duntoz as a purpose built racer. The Z-06 option consisted of a fuel-injected 327 cid V8, 36.5 gallon fuel tank, heavy-duty brakes, heavy-duty suspension, and knock-off wheels. The heavy-duty brakes consisted of drums with sintered metallic linings, power assisted and backed by a dual circuit master cylinder. “Elephant ear” scoops rammed fresh air to the drums and cooling fans spun with the hub.

For 1967, there were four versions of the 427 available. The first version, the L36, cost just $200 more and featured a single four barrel carb, 10.25:1 compression and hydraulic lifters. It was rated at a stout 390 bhp. Next up was the L68 for $305 which featured triple two-barrel Holley carbs (a first for Corvette) and was good for 400 bhp. At the top was the L71 with triple two-barrel Holley carbs, solid lifters, special performance cams, and 11:1 compression which was conservatively rated at 435 bhp. Extremely rare (only 20 were built) was the top of the line L88 for $948 more. The L88 featured new aluminum heads, 12.5:1 compression, and a single Holley four barrel carb rated at 850 cfm that sat on an aluminum intake manifold with a special raised plenum chamber. In addition, you got a transistor ignition and Positraction differential but didn’t get a fan shroud, heater, nor defroster. Chevrolet was reluctant about revealing the engine’s true potential and officially rated at only 430 bhp, but most experts believed that it in fact developed close to 600 bhp! In all, 9,707 big-blocks were built, meaning that 42.31% of all 1967 Corvettes were 427s. Transmission choices were relatively simple. With the L36 and L68, buyers could choose between the wide-ratio ($184) or close-ratio ($184) four-speed manuals, or Powerglide automatic transmission ($194). The L71 came only with the close-ratio four-speed. Rear end gear ratios ranged from 3.08 to 4.11. Other options included side-mounted exhausts at $132, cast aluminum bolt-on wheels at $263 and detachable hardtop for the convertible for $232.

The Perfect Camaro

The prefect camaro, in 1969 Chevrolet would have a grand idea, spawned by the creation of the sYc or Super Yenko Camaro, this car would be called the ZL1 Camaro, and would be the meanest camaro ever built, this car was not for the weak of heart, if you didn’t know what it was capable of it could hurt you very badly.

Only 69 of these cars were ever built, as far as I know, this number may not be right on the money, it can get a bit hard to find these numbers, if you search on the web you’ll find all kinds of different ideas about the production numbers on these cars, the one thing I do know is this, Chevrolet wanted to build a car to campaign at the NHRA, and this car was built specially to do their bidding on the race track

The sanctioning body of the NHRA had some rules about what they would or would not allow to race under their rules, the main rule was this, to be allowed to race the car had to be a regular production model, and this meant that Chevrolet had to produce at the least 50 of these cars to qualify them to race at the drag strip.

These car would go on to prove themselves beyond Chevrolet’s wildest dreams, they came form the factory with an all aluminum 427 CID big block monster engine, that was rated at 430 HP from the factory, which was a severe underrating of the actual power that the car had, but the all aluminum engine in effect made that car weigh about the same as if it had a small block, so you can imagine what would happen.

The car would be sold for what at this time was an outrageous price of $7,200.00, in 1969 Fred Gibbs Chevrolet ordered one of these Camano’s to go and race with, it was a special order car known as the ZL1 Camaro or COPO 9560 “Central Office Production Order” Dick Herrel was to drive the car for Fred Gibbs Chevrolet, and he would set a record for a street driven car during his run as a driver for Fred Gibbs.

The ZL1 Camaro would prove to be an amazing race car, not to mention, it was still a street car also, in street dress Dick Herrel would achieve 1/4 mile times of 11.05 and in full race mode, with the headers uncorked and slicks added he would achieve a 10.35 1/4 mile time on his first run.

Then he would reach a real high for a street driven car, mind you this in as bought from the factory with slicks added and headers uncorked or in full race mode he would achieve an all time high 1/4 mile time of 10.05, now how many cars do you know of from the factory that will pull that feat off.

I live in Salt Lake City, Utah, and have been in the automotive business for about 25 years, and during that time I have worked in all facets of the industry, plus owned my own shops, like I do now.
