Gear Vendors overdrive
#1
arrow 
I'm wondering about installing a GEAR VENDORS overdrive. Can this be installed in a fastback without any floor modifications? I'd love to see some pictures if anyone has them. Idea

I looked in to them. Sounds like the "Holly Grail" for guys that like to run deep gears. I never could get any real clear info, read honest. Lot's of sales pitches. I did run across one person on the VMF that had done one in a 68 ,I beleive. I think the main issue was the extreme pinion angle that was created buy the short drive shaft. I would love to be able to run one!

I ran a Gear vendors in my 88 F250. The unit worked very well. A buddy of mine runs one in his 55 Chevy 502 T-400. with no floor cutting. My brother is planing to use one in his 70 Boss 302. I was going to run one behind my C6 ,instead Ill be going with a AOD. You should not have to cut the floor. I would contact Gear Vendors in El cajon CA.

run an AOD instead and be happy with it. who knows how much longer parts will be available for it. i believe AOD parts will be available for a very long time.

X2 with the cost of just the overdrive you could build a pretty stout AOD. You'd get the capability of a lock-up converter to boot.

The cool thing about the gear vendors overdrive is that you can activate it in each gear, essentially making a 3 speed into a 6 speed.

Why would you take the 4 speed out of a Boss 351 to install an AOD. Install the Gear Vendors you will like it. The 4.10 gears turned into 3.25 on my F250 when the C6 was in high gear and the Gear Vendor was on. I had the unit in my truck over 4 years and towed a 16K 5th wheel toy hauler with no problems. My MPG went from 8 MPG to 10-11. I have a buddy that installed a unit in his E350 motorhome because he had trouble towing his inclosed trailer. He has told me that is was best investment he maid for the motorhome.

Thanks for the info. I could not believe that anyone would recommend putting a AOD into a Boss. To each is own I guess!Idea

4R70W's are really the way to go in my humble opinion guys. I am onto my next build now and plan to put one behind my 600+ hp 460 cid aluminum headed 72 Mach1. I spoke with mr. Art Carr this week and he turned me onto the guys that make the adapter plate to put a small block trans behind a big block. Art told me what I kinda suspected already after running a 4r behind my injected 351C which made 430hp for 5 hard years, the tranny NEVER hiccuped - not once: that the 4R70W is extremely tough once you do some (cheap) onboard mods to the pump spring. 4 programmable gears plus a lockup, HD OD bands, 2.84:1 1st gear and a Lockup(.67:1 od), its like 5 speeds! used V6 trannys are 2-400 and the Baumann controller for 5bills and you are cooking! I will do this swap for the 460, it will be smoking hot and cool all at the same time, oh yeah , I want to sequnetial fuel inject my 460 too. Sorry, I get carried away.

Keep us posted , and maybe start a new thread on the build... Data and experiences on newer mods is always helpful, to me at least Big Grin looking for a frontrunner to keep me out of too much trouble.
