More info on the transmission selection is the gear ratio 2.56, 1.91, 1.37, 1. That low first gear ratio should complement the 3.55 rear gear ratio we are planning to run. I’d like the car to pull hard from a standing start and still have freeway capability.
Using the Spicer transmission gear rpm calculator with the rear gear, tire height, etc. we should be just under 3K at 70 mph.

Here’s a chart and at 65 mph with our rear gear, tire height puts us at 2770 rpm smack in the middle of Balanced Power/Gas Mileage. Ha, gas mileage that isn’t this build!
Next up the standing start, here’s a free article that talks about Drag Racing Traction.
https://www.cartechbooks.com/blogs/t...making-a-pass/ About 2/3rds of the way into that article it talks about the Starting-Line Ratio. According to this an ideal starting-line ratio is 8.5:1. Ours is 2.56 x 3.55 = 9.088, is that good? Well, some more info says 4.375 Stroke & 3500 lbs. = 9.0 via the chart below.
I’m thinking that’s pretty good for a fat street Camaro with a fat driver.
Merry Christmas!
