Nice! That car is so awesome. Shakes the ground when you hear it run. I remember we tried to get the GM guy to do a burnout, but he wasn't having it. Probably too expensive with those GIANT rear tires!

Here's a few pics from the Impala Nat's in 2008:

great pics, love that big block!

that had to have a 4L80E in it, right?

that lady wanted that car.

that being said, $70k builds you that car with a built Nelson Racing Big Block...

660bhp

or how about a supercharged Big Block

750bhp

or maybe you like Twin Turbos (this might push the $70k limit if you're paying someone to install it all with a proper transmission and rear end)... but at over twice the power of the supercharged big block...

1600bhp

maybe you'd take a wash on the price difference

This is a boss looking engine fit for a black Impala SS for sure
