Too all of you 2.8ers out there...

[Jerriko]

A couple of weeks ago, I got these results out of my car at the strip:
-15.67 @ 85.1mph
That's good enough for 3rd overall in the n/a 3.4L listing on the timeslip page. It should also be noted that this pass was made without my headers installed and the trans was getting funky with the 2-3 shifts at WOT. I think the trans is fixed now. On the dyno, it works fine. Hopefully, I can get one more chance at the strip this year to see how much faster I can get her. Don't take any **** from anyone with a 3.1 or 3.4!

SO that was with the 2.8??? I wish I could have took mine to the track before it started chucking trannys, 3.42 rear, meaty tires, aluminum wheels, no A/C, spare jack, rear seats, accel ignition, all teh free mods no options. I allways thought 16's would have been very easy.

Nice time man.

Yeah, I just haven't had the time to install the 3.4 yet. With the cam I am using for the 3.4, I will need some serious tuning and reprogramming. I am currently using 3.23s.

You could go to a junk yard and find a good 3.42 rear for CHEAP!

We are covering rear ends at school and I am rebuilding a 10 bolt 3.42 F-body right now. Torsen LSD and all of the trimmings.

Can you find out what difference is betwen teh GM 1,2,& 3 series carriers? The $100 posi unit is in the wait [img]smile.gif[/img]

[Jerriko]

The main difference between the carriers is the design and the number of splines the axles have that are used with the carriers. The OEM Torsen for $100 plus shipping is the 3 series carrier. It has the same number of splines that the series 2 has but the 3 is far superior. The 1 series carrier had a different amount of splines and was found in the pre 82 GMs. Meaning this series 3 LSD is a great upgrade for the 3rd gen rear ends.

[3.4 slow to go]

SO, this is a viable item for us "earlier" third gens?

[Jerriko]

Definitely, its the one I bought.

[3.4 slow to go]

let me know when it comes in. According to the thread oin it over @ thirdgen, there might be a dispute over the axle spline count, 26 vs 28(required for the unit). And knowing my luck, I'd snap the diff cover bolts like the tranny bolts to find out. :mad: :mad: :mad: [img]graemlins/crybaby.gif[/img] :mad:

[Jerriko]

Hmmm,
I guess I should have checked that before I ordered the part. The spline count on the axles out of the rear end from 1989 is 26. I do luckily have axles at home on a rear end from 1990. They have different gears (3.23) and a factory LSD so I am hoping that the spline count is different.

[3.4 slow to go]

sell the gears & posi out of the 90 axle, to help pay for the gear 3.42 gear & slp posi install in the 90 axle. then put on your ride.

[Jerriko]

I went ahead and bought some Richmond gears (3.73). The runout on the old ring gear was .040". The tolerance is .000". But yes, some swapping will be necessary.
