hey guys i just got new frpp 4.10s with possi put into my 98, i just wanted to see how long the break in period is, the guy said about 300 miles, not as much for the gears but mostly the posi, ive went about 215 miles on it, u think im rdy to mash?!
Break in? Nah.... Just go out and drive in a figure 8 till the baby seal dies (shreaking noise from rear end) Once there is no more noise go out and hammer on it. Never had an issue with a clutch pak here.
