I would put David Williams owner of Fastlane Cars in St. Charles, MO. (greater St. Louis, area) up against about anyone for a quarter mile. He is just running a small block with a little boost
.
Seriously the dude turned 8.90 with old engine and now he has 200 more hp. I am thinking he has somewhere north of 800 hp at the wheels because he pegged the last chassis dyno and anything more than 800 hp was just a guess.
