Just curious: what gear/converter/exhaust got this done? I'm trying to convert a young brand X guy who is convinced that we can't go 11's with (almost) stock junk. 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. 4.10 gear, 28x10 tire, straight from the Summit catalog 10" TCI Street Fighter converter (around 3500 stall), 3" exhaust w/ 2 chamber (40 series) flowmasters. Running open headers never helped. Had a cheap 830 holley annular double pumper on it, list 9381. When it ran 11.80s it actually had a 3.91 gear and 26x10 tires. The ported heads caused traction issues (had SS springs then) so I moved up to the 28x10 tire and changed to the 4.10 gear the compensate. That made a HUGE difference in hooking the car up.
