Use this calculator to see what your starting line ratio is.
You can also use a different tire height to see how it affects the SLR
(see the effects of tire height change without changing the rear gear ratio)

SLR of New Tire  

A 9-10-11 range SLR is desirable.

The SLR of New Tire is what the SLR would be if
taking the different tire diameter were taken into account.
(like changing the rear gear or 1st gear)

For a clutch type vehicle this works good. Some racing automatics, the torque converter has an effect on the ratio. With a higher stall converter, the ratio can be smaller, making a rear gear able to be a higher gear for more top end.

by: George Reid
publisher: S-A Design, published: 2010-08-15
If there is one thing Ford Enthusiasts have learned over the years, deciphering which parts work with which engines is a far more difficult task with Fords than with many other engine families. Will Cleveland heads fit on my Windsor block? What is the difference between the two distinct families of big-blocks? What heads are available for use on my small block? Can I gain compression by using older model cylinder heads? Which pulleys should I be able to use on my engine swap? These are just a few examples of common questions Ford fans have. These, and many other questions are examined in this all-new color update of a perennial best-seller.
Thoroughly researched, High-Performance Ford Parts Interchange includes critical information on Ford's greatest V-8 engines and goes into great detail on the highly desirable high- performance hardware produced throughout the '60s ,'70s and 80s. By combining some of the best parts from various years, some great performance potential can be unlocked in ways Ford never offered to the general public. Following the advice in High- Performance Ford Parts Interchange, these engine combinations can become reality. You will find valuable information on cranks, blocks, heads, cams, pulleys, intakes, rods, pistons, and even accessories to guide you through your project.
Author George Reid has once again done extensive research to accurately deliver a thorough and complete collection of Ford V-8 information in this revised edition. Knowing what internal factory engine parts can be used across the wide range of production Ford powerplants is invaluable to the hot rodder and swap meet/Ebay shopper. A must-have for every Ford enthusiasts library.

The Design and Tuning of Competition Engines
by: Philip Hubert Smith
publisher: Bentley Publishers, published: 1954-01-01
No other book gives you better insight into the expert preparation of engines for racing and high-performance road use, whether your interest lies in street, oval track, drag, or stock car racing. The first chapters explain the fundamentals that govern high-performance engines: thermodynamic laws, gasflow, mechanical efficiency, and engine materials and construction. Understanding these basic factors is crucial to making correct decisions when tuning or modifying your engine. Actual engine preparation techniques are described in the middle section, including cylinder head work and balancing and blueprinting. The final part of the book focuses on modifying specific engines: American V8s, Porsche 911, Volkswagen Air-cooled and Water-cooled, Cosworth BDA, Formula Ford 1600, Datsun 4- and 6-cylinder, and Mazda rotary engines. You'll learn proven techniques to increase performance and reliability, and, just as important, which modifications won't give you meaningful gains.

ASIN: 1932494723
There comes a time in every automobile's life when the engine just doesn't perform as it should anymore. It may be burning oil, it may be leaking, the compression may be so low that it only starts on cold days, or maybe it just isn't very efficient anymore. When all of this happens, you have to decide whether to just dump the car and replace it, or add some new life to your old car by rebuilding the engine.
Rebuilding the engine in any used car, much less a classic, seems like a much more attractive option when you can save a lot of money by doing it yourself. Sometimes the savings are the difference between keeping your car or letting it go. If you want to keep you car running strong and lasting for years, this is the book for you.
A part of CarTech's Workbench Series, How to Rebuild Any Automotive Engine covers the basics of any engine rebuild in over 400 color photos of step-by-step instruction. Subjects covered include preparation and tool requirements, engine removal, engine disassembly, machine work and clean-up, short-block assembly, final engine assembly, installation, start-up, and break in. Also visited are the options of purchasing crate engines, remanufactured engines, and performance upgrades. This book applies to all cars on the road that feature an internal combustion engine. Spend a little on this book and save hundreds down the road.
