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) / 3456
This formula assumes 100% volumetric efficiency at redline, but street motors are more likely to fall in the range of 80 – 95%, depending on head/cam/intake/exhaust selection. Therefore, we should factor that into the equation by using an additional formula: Read more »

timloden How to choose the correct stall speed for your converter
November 29th, 2010 timloden 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 the stall speed before lockup occurs. If a vehicle is doing 30 mph at 1,500 RPM in second gear, when floored, the RPM will flash to 3,000 before beginning to pull hard. The pros and cons to this are important considerations. When the stall flashes, it will throw the engine into the power band and pull much harder than a conventional converter. The con is that, with the stock converter, top speed in second may be 50 mph at 5,500 RPM, and with the stall converter it will be around 7,200 at the same speed. The shift points will have to be considered as to speed to stay within RPM limits.
Installing TrimParts molded carpet

Classic Car Make / Model Identification Guide
November 15th, 2010 timloden During the 1960’s and 1970’s, the automakers used letter codes to designate which car platform the models were built off of. Unlike today, there were basically small, midsize and large cars with perhaps a special model of each available. Following is a chart which you can use to determine which model and platform your car was build off of, and that will help you identify which parts will fit your particular application.

Brake Pedal Diagnostics
November 14th, 2010 timloden | CAUSE |
REASON |
| Bleeder screws on calipers not on top. |
The bleeder screws on calipers must be at the 12:00 position on the caliper to allow all the air to escape during bleeding. A very common mistake installers will make is to reverse the side the caliper goes on giving you a situation where the caliper bleeder screw is facing down. It’s also common to use the wrong caliper on a bolt on disc kit giving a situation where the bleeder hole is shifted from the 12:00 position producing a pocket of air at the top of the caliper bore which can not be dislodged. Check your bleeder hole orientation. |
