Rework Tunnel for a 727 and Gear Vendor's OverDrive??????

[EbodyPro572]

Will the transmission tunnel on my 73 Challenger need to be altered to accomodate a 727 with the G/Vendors Overdrive unit???  Someone told me i would have some work in front of me.

To my knowlege yes... I dont think theyer making them any smaller... Carlwalksi would be able to give you details I'm sure

Just had to do a little air hammer on the tunnel on the passenger side.



Driver side cleared good.



Passenger side did not.




Afterwards




 If you have a TTI "H" pipe it will need to be relocated further back.

it is a tight fit & will need some clearancing to make it go

THANKS GUYS! The PICS are great too!
My transmission guy's telling me to just stay with the 727 and do 3.54 or 3.23 rear and not worry about the G/V o'drive.  I've got 4.10's right now.  I do want to drive on highway though.

[Chryco Psycho]

the GV is a good unit but not cheap , the 4.10 with the GV would work well

What do you think about running 3.23 or 3.54's and NO gear vendor unit?

[Chryco Psycho]

that works too , a whole new center section would be $1200 or so

Look for the 518 thread. I took the pics. I sold one of my 518s to a local Cuda guy that is having Tactransman put it in. I found 2 in a junk yard, one for $70, the other for $35 on Pick&Pull's 1/2 price weekend. The olny thing you would have to do is make the trans cross member like the transmission center did.  Do a google search on 518 and transmission center.

I have had the GV for 6 trouble free years and love it.  Best upgrade I ever did to the car.  3.55's become 2.76 at the push of a button.
