Re: Gear vendor's with 3:54 rear gears and th400?

I'm my old 73, I had a mild low compression 454, T400, & 3:21 gears.
The way that combo ran, I felt adding a GV wasn't necessary as most of my power worked between 1500-4000 rpms.
I could do 90 mph no problem but felt adding the GV may lug the motor.

I will be using a 14 Bolt with 3:42 gears and add the GV in my Longhorn along with a T400 and a mild 496 with 10:1 compression.

With this combo, I feel that I will rely more on the torque side to move the weight of this.
