Anything higher than 1:1 that enables you to run a 3.5-4.1 axles and end up with a 2.7-3.2 final has got to be a big plus both for a performance increase and an MPG increase.
About the only negatives I've read on the GV is the already posted reverse grenade.
Unless there is a better way, I think I'd wire a cutout triggered by the backup light circuit.
That is very unlikely due to shifter rules for track. One would really have to try to make that happen. (But I have seen stranger)Unless you literally threw it in reverse while moving forward or pressed the button while in reverse this isn't going to happen. As soon as you go come to a stop the GV disengages automaticly.
What was the initial cost of the used GVOD? 800$ to repair could still be a steal.
I have a GVOD and it's worth it's weight in gold.
I tow cars and trucks half way across the state in OD, on a dolly with my 2000 Dakota.
167,000 hard tuck use miles and never a trans issue (except maybe a delayed 2-3 shift when cold for that last 20K miles) despite the 1990's-early 00's reputation for any MFG having massive trans failures.
The OD turns my 3.92 axle into a 2.7 ratio. Best of both worlds.
The trick is to keep it out of OD until you are at or near cruise speed, and if you want engine braking, turn it off before you prepare to stop.
LMAO, we’ll there is a curve ball to end all curve balls!!!!GV says there race .78 is rated to 2000 horse for lower R
Yes. I have a very unusual build in an E-body Cuda. The reason I reference towing and diesels is because they better approximate load needs. The motor is 904 ci (6 inch stroke) that behaves more like a diesel. Thus inquiring about how trucks handle the torque and load demands. This is a race application with some light street requirements. (And I do mean "Light")

Yeah. Sorry about that. I should have probably led with intentions. But I started asking questions and had to back peddle a bit.LMAO, we’ll there is a curve ball to end all curve balls!!!!
More pictures please!
You want sence? Ah, well that's a different story. I wanted to chime in on OD strength. (Or inquire of) the Duster "Recycler?" That was due to its many Duster parts. Thus the name. It's a 74. Not the most sought after year for Duster. But it's solid. And has put plenty on their trailer. Not bad for single crab 451 NA. most I race usually has one shot of juice. The Cuda? It's a build that's hard to compare. That's why I sneak in on truck discussions. I will post more pics and better explanation once on laptop. And not 2" phone screen. But you are right. It just might tow decent?So, is the Cuda towing a trailer at Drag Week?Because that would start to make mucho sense!
The difference between .78 and .73 OD ratios is 200RPM at any given speed. (or 5mph)
That isn't a huge difference unless you are running some really severe gear.... Now I run 28's with 4.56's and 60mph is 2500RPm.
I agree. They moved to a rather boring rectangular rear lens. The 451 is a 74 block. And once had ported 452 iron heads keeping to a somewhat Super Stock build. (Or at least "SS Theme") But now I put B1/BS heads. So blew any SS fantasy. The new heads uped compression from 10.5:1 to 12.5:1 So now running 1050 4150 style HP carb metered for E-85. Exhaust smells kinda funny. (I think it smells a little like french fries) But cheap fuel to accommodate the higher compression.I like the power-bulge Duster hoods, but not a fan of the later tail-lights.
I agree with that. I was simply stating what I've seen people say about it right on this forum. That said, the GM transmission swaps would net OD ratios down in the high 60s. That's pretty impressive.
Yes. It is a bit nuts. The motor has a deck height of 13" and is 5" wider than a street hemi. After some measurement it was concluded it will fit inside the original engine well. And because the exhaust ports angle down more than a big hemI? Exhaust pipes are possible. I still may have to remove shock towers and go with coil over aftermarket front suspension. (Which may not be a bad idea anyways.) Would solve a couple other issues.That's crazy.
final drive for 833 OD .73.. Ford 5sp .68... Tremac is a .74. Whats the best OD ratio?.78:1 too high?
Kind of like shifting from 1st to 3rd.
Never drove one before is why I ask.
Depends on the combo and what you want to do with it.final drive for 833 OD .73.. Ford 5sp .68... Tremac is a .74. Whats the best OD ratio?
