increase 60 foot times

Carb tuning is a big factor in 60' times as well. Accellerator pump cams & squirters for 60'. Jet for MPH. Try to get both squirts (Holley double pumper) to finish at the same time and don't have it last any longer than necessary, otherwise you get a rich spot after the main circuit starts up. Lots of trial & error.

For reference, I had my 3,550+lb 360 Dart pulling 1.52 60' times while running 7.18 @ 93 MPH in the 1/8 this past weekend in the heat. It could be a bit better with more work, but it's consistent and I hate to mess with it.
