Default changing cars

my bro is changing cars.. was running a 85 cutlass weighting 2900 pounds....456 gears.... w/10 slicks and a built 355 and a turbo 350 foot braking it... 3500 stall....was running 12.50's.

now he going to a 75 vega thats weights 2200 pounds...456 gears....14 x32 tire and his 355 motor and a 3500 stall... glide w/brake.........


we are taking guess's at to what it will in the quarter mile?

Default Too little gear for the tire

I guess some where close to 11.90 at best for weight only because the tall tire with the same gear and a glide will put the engine to sleep at your power level, canceling most of your potential gains from the weight reduction. If you put the same 3 speed trans in the vega that you have in the cutlass you will go faster, 2 tenths or so.

I was figuring 11.8 with the glide , but thought the transbrake would improve the launch to about the same as a footbrake turbo. I also went with the smaller frontal area of the Vega vs the Cutlass. So, I'll stay with 11.7 as my estimation.
