Demon 340 vs Camaro 396 (400)

I just watched this one a day or two ago. That demon doing a 13.39 had me wondering if he had a 4" stroker crank in there or something. Pretty amazing time!

A 13.39 is nothing special for a nicely sorted 340. It sure wouldn't require a 4" arm or even a cam, just some gears and a tuneup.
