I tuned and drove Mike Musto's (producer of Big Muscle on Youtube) Black B-body with a 440 727 and Gear Vendor's overdrive for about a week. it was my first exposure to the Gear Vendor's unit. To me, the limited amount of overdrive it provides is not worth bothering with.
I went the modified Stage 2 (750 hp rated) 200R4 with a 3000rpm stall lock-up torque converter route in my '68 Barracuda with a Magnum based 408" EFI'd stroker motor. I used the SFI bellhousing to adapt it to my Mopar engine. With the lock-up converter, it's the closest thing to a 5 speed automatic I have ever experienced, and has a .67 overdrive with a 2.76 to 1 first gear. It's light, uses no computers and has a one wire to hook-up for the lock-up converter. I run mine with 3.91's. It's very quick out of the hole and will cruise comfortably at 80+ mph. Best of both worlds really.
The Stage 3 will handle over 1000 hp and either one will bolt up to any Mopar engine including the new Hemis with an SFI rated bellhousing, but not the Slant 6 at this point. It takes significantly less power to drive than the Mopar overdrives too.
I did have to notch the crossmember, but didn't have to hack up the floor. I love the combination and highly recommend it.
