[Edley Rondinone]

Pin Drive wheels---are held to the brake rotor by the big spinner in the center of the wheel. There are holes machined into the backs of the wheels. These holes match up with the "pins" protruding from the brake rotor. Once tightened with the lead hammer, the spinner is commonly wired to the wheels with a fine, piano-type wire, to keep the spinners from loosening up and falling off, which would then let your wheel separate itself from your Cobra. NOT a good thing!

A 3.00 gear ratio is a HIGH ratio, better for top-end speeds. A 4.11 gear ratio is a LOW ratio, better for quick acceleration.
A 3.54 ratio is a good "best of both worlds" ratio.
Your rear axles connect to the differential (center section) of your car's rear end.
A "Detroit Locker" is a top-notch, ratcheting 'pos-a-traction' add-on for your Ford 9-inch rear end.

The Camshaft is driven off the crankshaft, usually by a timing chain (but somtimes by a noisier gear-drive!) The lifters ride on the camshaft; roller rockers cut down power-robbing friction, allowing smoother operation. Camshafts use a number-of-degrees of duration, such as a 260*/260* intake/exhaust measurement, AND use an amount of lift, in inches, measured to the thousandth of an inch, such as .572 of lift. Generally speaking, the higher the numbers of the camshaft, the more power it makes at certain RPM ranges, and the higher numbers usually mean a "lumpier" idle. Think "potato-potato-potato"!!

The pushrods ride on the lifters, and activate the rocker arms in the heads, which make the valves open and close, allowing the fuel/air mixture to enter the heads, allowing the combustion.

You "stroke" an engine by changing/regrinding (making longer) the connecting rod journals on the crankshaft. Sometimes it is cheaper/easier to swap in a crank with longer "throws" on the rod journals.
