looks like i lost them ill pop the cover agin but it had 2.77a maybe that can help o and it came from a red 86 trans am 305 carb with a 700r4 trying to give all the info i can i dont want to lose my times but i do do aot of top end pulls (on the street )

 

Uh...as much as I would like to provide some helpful info there isn't really a question in there...what is it you're trying to find/figure out o.O? If you just want to put in better gears summitracing has them, and from what I have heard, I don't think it matters which size you get as long as its for a 3rd gen, but doublecheck that on the drivetrain board first...

 

well i have a min spool and i dont want it any more cops think im spening tires and i like the 9 bolt up if the geaing is bad in a v8 car what will it do in my v6 im asking cuse idk nd i kinda need some help on makeing my mined up
cods 0575 029001 bw kp 2.77a just want some in put will this be better at speeds of say 55+ and will it ower my rpms and what about my mpg and my hole shots

 

a 2.77 gear will lower your rpms per any given speed. mpg on the hwy should get better around town may or may not change much...lower rpms but, takes a little more grunt work from the motor to get rolling. that being said, "hole shots" will be non-existent. If you have a mini spool and just want to get rid of it, put a posi in it.

 

so do i just buy the ring gears and suff

 

you need a posi carrier to replace the mini spool one....and someone jog my memory on what exactly a mini spool is?

 

its basically a light weight, solid carrier. no spider gears, clutch packs, nothing...just solid.

you need a posi for the rear in the car or a gear set for the 9 bolt and hope the posi is good in it.

 

ok well i guess ill just sell it

 

from what i read up on them i wouldn't use one on anything other than a dedicated drag car...

 

ye im just going to take the spool out its my dd and im going to sell the 9 olt and but my money in to my supra and some in to my lsx motor for thr camaro
