Alternative-fuel sources and hybrid cars are all the rage today. Everyone from major automakers to backyard inventors is pursuing alternative fuels and energy sources. While the ultimate goal is generally to eliminate dependence on foreign oil, for hot rodders there is also the desire to invent and create a better-performing engine.
Crankshaft trigger mechanisms have been used in racing applications for a considerable length of time. In truth, they’ve actually been in service for decades. It’s a simple known fact that one of the best ways to improve engine performance is to ensure that the ignition timing is stable. That’s the whole purpose behind such a system, and that’s why racers regularly use them.

After recently purchasing a ’62 Thunderbird, it became obvious very quickly that the car needed a new engine. Our plan was to turn the car into a daily driver, and so, as long as we needed a new engine, we figured we’d add air conditioning to the car while we were at it. And if you really know your Ford history, you also know that the ’62 was the last model T-bird to come with a generator rather than an alternator—one more reason to consider an upgrade.
Producing horsepower requires two major ingredients, namely, air and fuel. Of course, the two must be supplied in the correct proportions and at the proper time; but improving power is a simple matter of adding airflow. Naturally, additional fuel will be required once the airflow is improved, but the first item on the horsepower priority list should always be more airflow.
Even though we all dream of blasting through the desert at 130-MPH like Robby Gordon, most of our 4×4 adventures take place at a much more reasonable pace. Unfortunately for our engines crawling along a boulder strewn dry river bed or climbing a goat trail through a mountain pass does not always allow enough airflow to keep our engines cool with a belt driven mechanical fan. Belt driven fans are designed to keep your engine cool when traveling down a street or highway not while crushing boulders at 3-MPH and 1,500-RPM. So what can we do to keep our rigs from boiling over this summer? Follow along with us as we install a pair of 11-inch electronic cooling fans along with a programmable fan controller both from SPAL USA.
This engine, and others like it, has opened up a brand-new chapter in the ever-evolving, wild world of Chevrolet power. By design it has a bore and stroke of 4.60 inches by 4.25 inches and Big Chief II heads, which are about 2 inches taller, that feature oval-shaped intake ports. This, they say, is for maximum cylinder filling. Years ago, creative racers would angle-mill heads to arrive at the desired combustion chamber size and to improve the valve angle in combination with the incoming intake flow. These heads are nicknamed “11-degree” heads, as they have been designed with a built-in 11-degree angle right out of the box. There’s no angle milling needed here. A special valvetrain is necessary, along with longer stem valves. Quarter Mile Performance feels that these heads are worth 200 additional horsepower over the very best “shorter” heads.

In 1981 this Jeep, that now belongs to Clinton Campbell of Dallas Texas left the factory floor with a straight 6, but he drove it away from Street & Performance with a 5.3 truck LS-1 type engine and a 4L60E transmission. Clinton wanted more performance, drivability and, with the recent enforcement of emission laws in Texas, he needed to be able to pass emissions.
This article dives into the unique modification of a 1967 Chevy Suburban by Mike Dempsey, who reimagined it into a shorter, Tahoe-styled version.
