estimated e.t.

Hi there guys, ive got a 69 swinger that is a prostreet car, getting ready to finish up the build. The car has a 12 inch tire on it, a 408 with aluminum heads that made 490 corrected horsepower and 508 lbs of torque matched with a 4 speed and 8 3/4 rear with 4.56 gears. Im wondering what the weight would roughly be and what kind of numbers i could expect with this combo. The car is mostly going to be a red light warrior maybe see the track a couple times a year. Just curious to see what itll do. I had a turboed 4.6l 2008 mustang gt that made 477 to the tires and felt like a quick car, weighes in at around 3850, wondering if this swinger wouldve beat that car. Thanks guys.
