LS1 engines have been touched by the hand of God!!!
Unfortunately he (she if you get down that way) forgot to touch anything else on it.
To make the Mustang and TA being talked about equal you have to put the $6K difference between them back in to the Mustang. Once you've done that there's no question that the TA no longer wins the race, it's just up to you which you would rather drive. Guess which one I would choose?
I choose the Mustang.
