GV overdrive for a BB??

[tooslow]

I am looking at for my 440 w 525HP
Does anybody have experience w this unit? installation ect....
I will have to shorten my driveshaft/no big deal

I put a gear vendor in my 68 Dart very happy with the unit. However the unit didn't fit in the tunnel as they said. I had to modify my trans mount to lower the trans down about 3/4". When I called gear vendor they said I might have to enlongate the crossmember holes about .100 but that was not nearly enough in my situation.

I would go to a AL shaft while your at it, you're adding to driveline weight so might as well remove as much as you can. . .

This is what i do with my customers with GV instals

I have the GV on a 727 with well over 550hp. You will need to mod the tunnel. I love the unit when it works. I have had some issues with ecu control. Seems to be working well now on the new ecu. I run a toggle switch so I can reset the unit on the fly if needed.
