With this combination (473 cubic inches, 3070 lbs) we qualified with a 8.491 et at 158.09 mph at Tom's Heads up race at Norwalk in 2015. Still not as fast as Picket's wagon. So was wondering if you guys have an opinion on the improvements I can gain with the following changes:
Dry sump
New custom built headers
Sheet metal intake
Seal hood scoop to the carburetor (Ram Air)
Thanks for the help

John,
I tried alcohol and got no improvement.
