Shoot, my cuda ran 11.80s at 112 mph w/ stock untouched (other than a valvejob and new valvesprings) 906 heads on a 10:1 pump gas stock stroke 440 w/ the 509 MP purpleshaft. That was at 3700 lbs in full street trim.
A set of home ported 915s got it down to 11.40s at 117 mph.
It did have an edelbrock performer RPM intake and headers, but ran good for a bunch of junk.

I look at a lot of these aluminum headed strokers running in the 11s and think they're leaving a LOT on the table.
