As far as the weight......unless the laws of physics have changed...adding weight to the back is better than adding weight to the front

The problem of many is the lack of understanding of physics.
Physics is more that the laws of leverage or fulcrum and that is were many miss it. The center of gravity of the car has to be considered the same as many other factors. Just because a car has a very high wheelstand, it does not mean the car is fast.
One item people have to understand the concept of wheel speed. Hitting the tires hard on the launch, you hurt the wheel speed.
About transmission 1st gear ratios, the selection depends on the engine powerband. You have to optimize the recovery of the engine Going from a 2.52 gear ration to a 1.00 high gear ratio, due to the RPM drop, is not for all engines. You also optimize the launch with the rear end ratio and torque converter flash and lock RPM's.
By the way, I wrench a Stock Eliminator small block car has does pull the wheels off the ground, carries them without losing wheel speed and the 60's are better than many of the big block cars in the class in the mid 1.30's. None of the weight is on top or behind the axle. I also wrench a Comp Eliminator Super Modified car that has all the weight ahead of the rear axle and 60's are in the low 1.10's and I know that at the right track it will got high 1.0's.
