need help with figure out what converter stall speed!!! - 07/20/09 02:37 PM
well i raced my car last week and i think my car is way over stalled. I am useing a 9-1/2 ati converter that was soposed to stall 38-4200 behind a 340 small block. but in my 73 440 dart i can make it stall in frist gear around 5200. at the track my car would flash stall around 5600. my car seemed to run the best at shifting at 6200.my best pass was a 11.85 at 110.9. I was crossing the strip right at 6000 rpm. does anybody know how to figure converter slip? I am useing 4.10 gears and 275/60/15 m/t street radiels.this is a street strip car so what do you guys recomend for stall speed.thanks Mopar65
