1990. We were all a lot younger then & some are gone now.
...
Al's 400.6 mph run was at World of Speed, I think? Top Time at Speed Week was 393.xxx.
What happened on the return run? As far I can tell Al did set a couple of records at World of Speed that year, but not using the 400.6 mph run.
And for a bonus point: who else ran over 400 mph in 1990 (wheel-driven)?
