Still running in a D50 down south drives it to the track.


Second car was Brads 422" w9 motor
Was built for spray and we went 9.40s on pump gas 140mph
3150 lbs

I don't feel it's hard to run mid 9s in 2900-3100 lbs car. On pump gas
The pump gas 457" deal I just did should run low 9s




I was at 3215 when I ran those numbers. It was 1.36 / 6.09 / 9.46@142.
Drove it all over and ran 9.40/9.50s at Atco, Cecil, Maple Grove in the summer heat. Would slow the car down to race 10.0 index.
