Sorry it's taken so long to respond. I can't find the pictures I had of the Gear Vendors installed in my 69 GT350 I believe they were on my last phone that got destroyed in an accident.  I'll try to take some when I get a chance and post them

Hello

I have a GT 500 with built 427 side oiler stroked to a 488, dyno 592 HP and 609 torque, 389 Detroit locker, installed a Gear vendor, reasonable easy, no mods or cutting, remove tail shaft from 4 spd bolt it on, some wiring, push in clutch hit a button anytime over 40 mph and she goes into over drive. I think from 389 to 260, not that expensive either. Automatically releases under 40 MHP. No issues with handling the torque or HP

I thought you had to cut the driveshaft?

Doog 427

Yes, need shorter drive shaft kept orig and had new one made

#48
+1 for Gear Vendors.

My KR has a 427 side-oiler punched out to 468 cubes; made 580 hp and 607 torque on DenBeste engine dyno.
Stock 3.50 Traction-Lok.
Stock Toploader.
Custom (shorter) driveshaft.  (Replaced the Dead Nuts On driveshaft because I didn't want to cut it.)

The revs at 75 with GV OFF is an indicated 3450 RPM.   With GV ON they drop to about 2700 RPM.  The speedometer and tach were recalibrated three years ago, but I can't swear they are 100% accurate.

I agree that you can spin a good BB all day long at 4000 rpm, but I guess I am getting a bit soft because I simply like the lower revs when I'm cruising on the freeway.

I do track the car occasionally at club events, and sometimes use the GV to lengthen the pull on a long straight without revving it to the moon.  It's not a race car, but it has a lot of power and the extra leg length of the GV just makes it that much more adaptable to use.

Unit has been bulletproof so far. Super easy to use. I installed a Hurst T-handle shift knob with thumb-button to switch the unit on/off.

(BTW: I have no association with Gear Vendors. Just a satisfied customer.)

Do you push in the clutch to engage O.D?

Is there exposed wiring on your Hurst shifter lever arm?

You can pick your final O.D. Ratio, correct?

Side-Oilers

Yes, push in the clutch WHILE engaging or disengaging O.D.  Push the button, then let out the clutch.

I cut a groove along the length of the shifter, and recessed the wire.  I can feel it with my finger, but can't see it, when seated.

I believe all of the GVs have the same ratio.  0.80 IIRC.
