What should I expect from 450hp?

it's your cam.My friend built a 408 with a small cam and 3.23 gears and could get massive tire spin in three gears.
He also has a 396 camaro with 3.31 gears.Has raced them side by side and his 408 dart walks away from the camaro until about 80 mph and then the 396 camaro runs him down and pulls away from the dart
With gears i think you would have a nice quarter mile performer!
