What does an X-pipe do? X or H both are balance tubes which are meant to help the scavanging effect of your exhaust system. X-pipes are less invasive towards flow and tend to yield better Peak HP…H-pipes actually cause a bit more turbulence but to the effect of netting slightly more backpressure increasing TQ. Honestly [...]

Feedback from customers over the last 11 years, indicates mileage improvements of 30% on the low end to over 70% in a couple of well documented cases is about the range you should expect from a conversion to one of these overdrives. For example, if you now get consistently 12 miles per gallon, expect to [...]

The answer is YES. Vehicles that came from the factory equipped with these transmissions did not use a computer to control the transmission. The confusion comes from the fact that the computer in the later models controlled the 12v circuit to the transmission for converter clutch lockup. You do not need a computer to run [...]

Camshafts can be made out of several different types of material. Chilled iron castings: this is a good choice for high volume production. A chilled iron camshaft has a resistance against wear because the camshaft lobes have been chilled, generally making them harder. When making chilled iron castings, other elements are added to the iron [...]

Passenger car and truck oils are formulated to reduce emissions and provide longer drain intervals. This has been done by increasing detergents and reducing anti-wear additives, but your race engine operating under high load and high RPM conditions needs high amounts of anti-wear additives (Zinc and Moly) to create a sacrificial additive coating that prevents [...]

The carburetor itself has perhaps the most pronounced effect on fuel consumption. Since each carb comes pre-calibrated for a certain cubic inch and RPM range, the best place to start is with the right size carburetor. You can calculate the required CFM using following formula: Theoretical Carburetor CFM = (Engine CID * Maximum RPM) / [...]

A normal converter has a stall, depending on vehicle, from 900 to 1,200 RPM. As the stall speed increases, the lockup increases, but with normal driving the vehicle will accelerate with small load fairly normally as long as the stall does not exceed 3,000. When max power is called for, the stall will flash to [...]
