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.

Way too many variables to be precise...but,

490 "corrected" hp on a engine dyno wants me to think about 450, in the real world.....installed in the car. As far as weight, it's a little bit of a crap shoot not knowing all the particulars. So i'll just use a round figure of 3200 with you in it.

So with the above said, I can see low 11's @ the hi teens, as a possibility. Keep in mind, this is a rough guess at best, and a lot of things will have to be right, not just with the engine, but the car itself, suspension, tires, wheeling that 4spd, etc.

As far as taking on the Stang w/477 @ the rear tires.......likely not! Even carrying 3800lbs.


Good Luck! at least this should get the conversation started.
