FWIW my crawl ratio is right at 75 in first gear and most times it seems a little low for me so i end up doing most stuff in second.
If I go with 5.38's the crawl ratio is around 64 and change.
I think you would like that 64
My crawl ratio is either 58 in 2.7:1
Or, 81 in 3.8:1
I run mostly in 2.7 and if I need more finesse go to 3.8. Your number is kind of in the middle.
If I’m behind Clark I go to 10:1 ...that’s a ridiculous 215 crawl ratio
