[Zoom This]

Well.....I saw a lot of quantifying information here and I can tell you what my SPF has done. Last year my good buddy and me took an 8 day/3k mile road trip around the west. On our way back home I decided to see what the "Mighty 418" would do, on a whim. It was about 7 am on a beautiful morning. Blue sky, not a breathe of wind, 60-65degrees and very dry outside. 100 led to 135 led to 150 mph in no time. At that speed in a convertible things feel VERY busy. My favorite hat was pulled off my head at 135. The car had a passenger and about 100 lbs. of luggage, tools and spare parts in the trunk. Throttle was at about 3/4 to the floor at a 150 mph cruise. Tach read about 4400 rpm with a TKO 600 5 speed and .64 overdrive. Rear axel is 3.73:1. Motor makes 478 RWHP or around 550 at the flywheel. This was the first and last time my car will do 150 mph, with me in it anyway.
