But go jump on the new 4.0 with a stock 5.0 ,and yu will get ur feelings hurt.
You should have done a lot better than 2 car lengths. Mach's are mid to high 13 second cars bone stock right? Seems like most 5.0's were running mid to high 14's stock, mine ran 15's flat in stock trim (Hawaii air not so good as Englishtown).

Besides, who has a stock 5.0 these days? Nobody I know...
