03/04 Cobras with 600+ RWHP/TQ and 3.27s

[HURTNEM]

I asked this question about a year or so ago in another section and only got a few replies. Hopefully more folks will see it here. I'm wondering how many of you have dropped down to 3.27s or know someone that has. How do you like them compared to the stock 3.55s (pros/cons)? Thanks.

what's your goal?

more on the top end? little less grunt down low? both?

Traction on the street. You can't get your doors blown off by a Honda Civic from stop light to stop light and tell him to follow you to the highway for a 40 roll so you can get him back lol. Even with Drag Radials 1st gear is pretty useless with stock gears at the HP/TQ level especially with IRS.

If you get beat by a fwd honda from a dig with a rwd 600 hp cobra then you cant blame the car for loss of traction. I have had both 355 and 323 gears and i went back to the 355s. With the right tires the power is very manageable (i made 618/583) as long as you arnt power shifting the tires off each shift. Also it is possible to launch from 2nd to help with spinning out the hole.

^^^I believe you meant 3.27s, right? What made you go back to 3.55s? How did you like the 3.27s with a 26" tall tire?

 

[ArmedSuspect]

gotcha. not something i would consider but i see where you're coming from.

seems like enough guys with 600-ish hp and 3.55's are killing it on the streets. re-gear (up or down) doesn't seem to be super popular for the Terminator.

I run a 315 mickey Thompson et street drag radial 100% on the street and love it. I just try to avoid any wet roads lol. You arnt going to kill yourself either way. I just prefer the 355s because it seems to give me a more "suck to the seat" feeling. Never got to run the 327s at the track so im not sure if it would make a time difference there.

I have just about 595/597 running 3.27's. Traction is a little better but the main reason i switches was for three reasons. I do the 1/2 mile roll runs and i have won several races because they had to shift at the end of the 1/2 mile and i didn't. I run at a local 1000' track and with the 3.27's i can leave it in third gear. I open track my car and at most tracks i visit i no longer need to shift to the next higher gear at the end of the straights.
1st 55mph ......................................................................................
2nd 85mph .....................................................................................
3rd 115mph ....................................................................................
4th 155mph .....................................................................................

^^^Traction is only a little better with 3.27s vs 3.55s on the street? I was hoping to see a big difference lol

People have had good results with toyo r888's to get back some traction

 

[gnatsumarboc03]

Im curious of this too, as I want to get rid of my 4.10s

I make 580/541 and I run BFG KDW2's on the street and I can go full boost in all gears. No power shifting obviously. I love the 3:55's. I wouldn't change them.

^^^Most folks can't go full boost in 1st gear with the stock pulley on the factory Eaton with those tires, so I don't know how you do it with a 2.8KB. Some guys have all the luck I guess lol
