It's not that hard.Figure a 15" radial has an outer diameter of about 27". That means the tires circumference is about 85 inches. Roll the tire one full revolution and it should travel 85 inches. Now, let's say you can get the engine to turn pretty fast. A built V8 can do about 5,000 RPM. Since the transmission in high gear without overdrive is 1:1, we don't need to consider that. Thus 5,000 RPM at the engine is 1548 RPM at the tire. 1548 * 85 is 131,580 inch/min or 124 MPH. With a 2,02 rear ratio, you're at 199.Best regards, Frank On Dec 12, 2007, at 3:38 AM, dansgarage@xxxxxxxxxxxxxx wrote:Hi John!...how would I calculate what the TOP SPEED and TOP RPM woould be for my '66 LeBAron with the stock 440 engine, 3.23 rear, stock 15in. wheels and dual exhaust? there's probably a formula for this. I'd appreciate you sharing that. Feel free to email me directly at "dansgarage@xxxxxxxxxxxxxx" if you'd prefere so we don't bore the rest of the IML.Thanks a bunch! Dan Melnik ---- "John L.

Those are baddriving habits which have nothing to do with realizing the potential ofthe engine. Public roads are a community of people who have to worktogether to get along. If someone wants to find out how fast their carwill go, they need to make arrangements with a race track, notexperiment with fast driving and a different braking system on a publicroad. The excessive burst of power available to Imperial Owner's is there for safe passing on two lane highways and smoothly merging with high speed freeway traffic.
