    31" spline

     



    Will a 28" spline in a 9" ford with 4:11 gears hold up for both street and dragracing with a 350 HP engine and 375Lbs torque or should I go with a 31" spline?

    With street tires, a 28 spline should hold up fine if it's in good condition when it's installed. Heck, I've ran mid 10's with a big block and slicks on 28 spline spool and axles.... Twisted and broke an axle eventually, but it made a lot of passes before "retiring". They are a tough unit.
