I had a chance to drive a 409 cubic inch stroker a couple of weeks ago. Owner said about 450 rwhp and rwt. I timed it from 40 mph in 2nd to 100 mph in 3rd. Last weekend, I did the same in my Z06 and I was about 3/10s of a second longer to 100 mph. Not too bad for a head and cam Z06. Does anyone know what distance that would be at 100 mph? I think the owner would be a little suprised at how close we'd be.
