Geez , I just wanted to know how much.MOTOR- POWER- TORQUE-SNOT -an 8 1/4 rear would take....Sorry I used the wrong word ...guess I should have said torque, but I thought all you gear heads out there would get the message..Car is 3000 lbs. motor is a 493 stroker.never been dyno tested..moved a 3600 lb car with 3;55 gears. with poor tracion .. 1.67 60 ft. to 11.35 at 119.5..now that motor is going in a different car that has 8 1.4 rear..foot brake 3000 rpm stall.. just wanted an opinion on rear life.. thanks everyone for your input..
