Wow not bad, but all that and hes hoping to hit mid 13s
Nice set up for the street but not enough to even talk smack to the most lightly modded buicks. I'd love to know what your mods are? don't tell me its gonna have a holley 750 double pumper with mechanical secondaries and that will get you close to 500 hp with the stock manifolds?
