Has anyone heard of the lingenfelter 427tt it can go 0-60 in 1.4sec. 0-100 4.3sec. 1/4 mile 9.2sec.(it's a freaking automatic not manual) and the topspeed is 240mph. or higher so that's faster than a mclearen f1 for less than 1/4 of the price. That should be enough proof for everyone that american muscle is the best.
