Load-O-Matic Distributor & Spark Control Valve
How The Stock Load-O-Matic Distributor Works Here is a little clarification on how the "Load-O-Matic" distributor works, along with the infamous "Spark Control Valve" (or SCV). Not only is it important to know how they work, especially if your planning a carb swap, but how they work in... -
Flow Testing the "Log" Cylinder Heads
This tech article is a "work in progress". Information will be added as it becomes available. Over the past few years we've flow tested several Australian 250-2V cylinder heads, as well as our own Aluminum cylinder heads. However we've always wondered how the cast iron "log heads" stacked up... -

The most common mistake when building a performance motor, whether it's a V8 or an inline six, is selecting a carb which is simply to big (or over-sizing the carb). Don't fall into this trap, bigger is not better.......

When Ford introduced the Mustang in April of 1964, the base powerplant was the Falcon's 170ci six with 101 horsepower and 156 lb-ft of torque. Later that year, in August, Ford updated the Mustang's engine line-up with the seven main bearing 200ci six as standard equipment. Both the 170 and 200ci...
UPDATE 9-7-07
Classic Inlines is developing an aluminum head for the Big Six (240/300ci) Ford inline six engine. At the present time, we are having the pattern maker re-work the patterns as we were not happy with the results. For some strange reason, they made the head similar to a shoe box...
The primary goal in designing and developing a new cylinder head, is the reduction of total ignition advance, while simultaneously increasing the air flow capabilities and chamber efficiency. By utilizing the best engineers and pattern makers, foundries and machinist, as well as the latest...
This page will give you a brief overview of our new aluminum cylinder head for the Ford small inline sixes (144/170/200/250ci). We will touch on our reasons for choosing the OZ250-2V platform (rather than a cross-flow) as well as the advantages, the flow test results, and estimated performance...

Classic Inlines offers rebuilt 1100-1V carburetors which are re-calibrated to eliminate the problems commonly found in factory calibrated carburetors, such as hesitation and/or flat spots. We currently have a fairly large inventory of 1V carbs in stock, which are rebuilt and ready to ship...
High-performance mufflers and exhaust systems are as much about looks and sound as they are about horsepower. Most people want mufflers and exhaust systems that look and sound as good as they perform. That's easily accomplished when the parts are new, but how about two or three years down the...
It has been published that headers will not work with A/C, this is an incorrect statement. What is true... is that headers will work with either Stock or After Market A/C, but it is not a simple bolt on upgrade.
Modifications are required to the compressor and/or alternator brackets to achieve...
One of the most common problems with the small six is blown header gaskets and/or exhaust leaks. However they can be minimized by following proper installation procedures. The use of locking bolts may help, but even then, leaks can and will occur if you don't torque the header flange bolts (or...
Do I really need a port divider? Will I get better performance or an increase in mileage? Will my exhaust system sound better with the port divider? Will a port divider help to prevent blown header gaskets? These are questions that have been asked and discussed many times on the fordsix forum...
Selecting the Proper Valve Springs
Valve springs are one of the most critical components of your engine. It is very important to match the camshaft and it's potential RPM range with the correct spring rate. We will attempt to explain it in this article, but first lets go over some valve spring...
The Pertronix Ignitor® converts the older points-type ignition system on classic cars, to a solid-state electronic ignition system that's completely concealed, providing a stock appearance. The kit includes new micro controller that installs in just a few minutes. Generally, it installs just as...

Many racers and engine tuners have opted for state-of-the-art diagnostic equipment but have forgotten one of the simplest, as well as one of the most accurate tuning tools...... the vacuum gauge.
When using any vacuum gauge keep in mind that they are all calibrated at sea level and read-outs in...
