Re: Gear Ratio
I'm beginning to wonder If I am reading what you wrote in your first post correctly.
Are you saying that you can only get up to 15 before you have to shift out of low gear ?
Or are you saying that the truck easily runs up to 15 and above before you need to shift out of first gear?
Most of the time with a truck 4 speed with the 7 to 1 low gear we don't start out in first unless we are in a situation where we need the 7 to one reduction. Pulling an incline, pulling a load or both. I will in my 77 with the SM 465 because with the flatbed and hoist and maybe 800 lbs of extra metal on the frame it weights over 8 K empty .

77 C 30 dualie, 454, 4 speed with a 10 foot flatbed and hoist. It does the heavy work and hauls the projects around.
