does anyone know anyone in long island with 4 corner car scale?

I'm interested in what you are up to wanting to scale each corner. These G bodies are notorious for front end weight so it's hard to get the bias and cross you'd want. Remember to unfasten one end of your shocks when weighing the car.

just trying to get a handle on this new power plant I installed (went from small block to big block) . I hope to get most of the weight on the back wheels.

I don't want to discourage you but the G body circle track we built we removed all the inner fenders, wheel wells, reinforcements on the hood, header, lights, bumper, windshield and vacuum brake booster and with a SBC we still could not move the weight to the back. We had to use lead weights to move the weight to the back so we could get the bias and cross set up with the number we wanted.

Its a start point to see where I'm at in weight with the car and go from there . So far I got it to launch straight by adjusting the psi of the passenger side air bag. Around 3-4k pull I can still make the back tires spin in 3rd gear at 60-70mph i can compensate with timing to control some but i think i can get more weight transfer.

Back when I raced my T-type 3 time a week, I measured each corner on the track scale one tire at a time and recorded the numbers. I also did a front and a back and did with airbag air and without airbag air on the Right and left rear tire before and during power braking/turbo spooling.

The data showed the Airbag preloads the right side (and unloads the left) so the weight is equalized during launch. If the Track scale is level with the surrounding pavement, you should be able to get good side/side data. If its 1" or more above/below the surrounding pavement, front/back should be good but individual tire data might go wonky, so you'd have to do front, back and the entire sides and calculate the individual tires.
