I am building a 406 right now that I will be expecting numbers in 500s. behind the motor will be a T-5 and 373 posi in the 10 bolt rear....I was just wondering from personal expereience and from what you have heard. How long you think my 10bolt will last? I am really worried, but dont have 2 grand to drop on a rearend, I can barly afford finishing my motor

are their ways to beef up the 10 bolt?

Look at their axle tube brace kits and rear end stud kits with girdles.. get a solid pinion spacer, weld the axle tubes all the way..But running a stick.. you could drop a 2k launch and blow it out if your tires were really sticky.. You won't want to run with slicks and a 10 bolt and a manual.. That would be just asking for trouble...

 

You T-5 will break before the rear. You will not want to run slicks or powershift because it will all go boom, the first time you try 1/2 throttle or more.

 

One holeshot on slicks and u can kiss your 10 bolt and t-5 goodbye. Tires that wont hook will be the only thing saving your drivetrain. Start saving....good luck.
