On top speed topic, I get a laugh out of people telling 'old' stories of going 150+ in 60/70s muscle with non OD trans and rear end gears that couldn't even do it, or suspension control to sustain the speed. No point in arguing.
When I was 18 my dad and I got our 1969 mustang on the road. Full resto, new everything. 351, Top loader, 3.50. At 100, you needed both hands and both lanes, and that was almost 5k in 4th. In comparison, my 87 mustang with suspension work and rated tires would bury the 140 speedo and sustain that speed in control for distances longer than I ever should have driven.
Now old, I try to avoid such activities but still do shorts bursts of triple digits often enough.
