Evening at the track

Isn't that faster than a new factory Corvette or Challenger that costs $60K?

You got that mixed up as the stock Corvette times were in the mid 12's as of 2012
Now for the Challenger, we'll have to wait for the new 392 supercharged version :) as the older one still have to catch up to the Camaros :(

And this post with his Slant 6, it's awesome and I appreciate it...
