Thank you for the help and comments! Just wanting to make sure I'm on the track before I start making these changes.
The truck has a 383 with 10.5:1 compression, 200cc aluminum heads, roller cam, etc. Should be around 450HP at the crank. Trans is a Turbo 350 with a converter that flashes to about 3500 with the current gears. The rear gears are 3.08
and an auburn posi but hopefully down the road they will be switched to something more desirable. I have some 15x10 wheels with 325/50/15 drag radials for track use.
Hoping to break in to the high 12's at least.
Would the weight of the battery be more effective in the place where I have the jack located? The jack wont be there at the track so that spot is fair game. It will probably be much easier to get the battery in and out in that spot if it will fit.
