there was a guy around 2007 or so named rygenstormlocke that got a 4.0 v6 into the 10 second 1/4 mile. I think he had a turbo setup. I think somebody did it with a vortech supercharger setup too.

you'll hit 14's with engine tuning and gears

I just found his post. He hit 10's with a built motor, a turbo, and 75 shot of nitrous on top lel.
