Was this while towing a boat?

My bass boat went 100mph a couple of times......but it was on a trailer behind a duramax

That would probably be Ed Voss (Worldrecholder), current C/C production land speed record holder at 221.871 MPH at Bonneville.

Wow ! That is certainly built for speed! I have to find a video of that thing on its run!
Thanks for the reply!

When I was about 17, I took my 73 Mach 1 out on a long stretch of deserted highway to see what it could do. I had recently built my motor and trans and wanted to see what all that money and effort got me. I always told people it topped out at 140, but honestly all I knew for sure was the speedo needle hit the trip odometer reset rod, which I estimated to be about 140mph. This was before I added the ram air set up, so it still had the block offs in the vents, and I remember feeling like it was really light in the front end. I had 245/60s on all four corners, but I knew I definitely did not want to make any steering adjustments at that speed. This was before I upgraded the rear differential, so it still had the highway gear in it. I am sure I would not have been able to reach that speed after I upgraded to the posi with the 3.89 gear ratio.

My current car, although I know everything is new and slightly beefed-up in the suspension, will never see any attempt at speeds like that. First, because I am a little smarter than that now, not much but a little. Mostly, because this engine is much tamer than that engine was, and this car came with a 3.00 gear, and plan to upgrade to a 3.25 or maybe 3.50 over the winter. I have had the car up to 100 and it felt pretty good though.

In 1978 I was driving my Boss 429 to Ft Lewis at around 4am. As I came around a curve in the freeway into a straightaway, I pushed the gas pedal down and the tach went up a little over 7000 and the speedometer was pointing straight down. The engine was singing, sounded sweet. I used a gear ratio/rpm calculator to figure the speed at a little over 140 mph. The car felt solid. The engine was built by Holman and Moody using mostly Ford nascar parts. The suspension was stock and still had the original F60x15 Polyglas tires and factory 3.91 gear ratio. I am still pissed at myself for selling that car.

3.91 gears would be singing at that speed.

I can only imagine, I am stilled pissed at myself for selling my 73 from H.S / college days and it was just a H-code 73, great car in its own right, but certainly no Boss 429.
