It's really more heat cycles than miles. You don't want to put a ton of miles on it all at once. I'd say 5 or 6 ~20 mile trips would be fine, while allowing enough time to let the rear end cool off between trips. After you complete the heat cycles, you can drive more aggressive. The 500 mile rule is more for fluid change than break in procedure. Be sure to run conventional gear oil also. I run Castrol 75-90 (or maybe its 80-90) Hypoy-C gear oil.

 

sweet...thanx for the tip bro

 

yeah just give me a call Kasey
Thanks

droppin it off at 7am tommorow!!! cant wait, i should have it back tommorow afternoon.....anyone have the t/a diff cover, im thinkin i want it!!

 

its done!!! now all i have to do is get it back to wheatley to retune it for my 410s, and get rid that annoying abs/brake light crap

 

i know that is annoying

how does it run? should feel alot stronger just driving normal

 

it wont run right until it's tuned for the gears

 

heavy chevy, i can tell a big diffrence, i had 323s. cant really lay into it for 500 miles, after break in im putting on my TA Performance cover and new fluid. Wheatley tuned my truck, and i have an appt with him tomm evening to retune it for the gears. guess im gonna drive around houston this weekend to rack up them 500 miles!!!

 

i know what you mean, even before my truck was tuned for the gears it felt great! but it will be like night & day after the shift points are changed

break-in is truly a pain

 

Thats no BS!!!!
