I've got a 1968 Camaro with an LS3/4l65e. 8.5 10 bolt rear end and 275/40-18 rear tires. That's a 26.6" tire.
I'm gonna get the rear end rebuilt, regeared and add posi.
The car is gonna be a cruiser, no racing in its future.
I plan on a lot of highway miles.
I was between 3.42 and 3.73.
I know from the calculators there's only about a 200 rpm difference between the 2 at highway speeds.
Which would be the better of the 2 for off the line? I know 3.73 will be better off the line but is there gonna be a huge difference between the 2?
How will the first and second gear ratios in the trans effect the overall performance?
