I like deep gears and avoiding highway travel, but that’s just me... now saying that, I can vouch that hot rpm happy small blocks in heavy vehicles work very well with 4.56 gears.

What is the OD ratio again? Truck OD trans is different IIRC. I keep forgetting. CRS!I totally get that;
I got me a GVOD so I could run any rear gear I wanted to, and I had a shed full of accumulated pumpkins.
My 367;blew up some ex race-gear 5.38s; and zinged off a couple of teeth on some used 3.91s; I traded the 4.10s for 3.55s,sold the nearly new 4.30s;and no takers yet on the 4.88s; so I totally get you,lol.
Finally I got the Commando box with the 3.09 low, and re-installed the 3.55s. Then it was , bye-bye to the byway blues, with a 2.77 equivalent overdrive gear.

So since I have you this far, would you be so kind as to break out the calculator and do a quick figure on the ratio changes for the 4.10 & 4.88's please?
Thank ya AJ.
No doubt GE, no doubt.
Even better when you run a ride around 3K or less with a big cam.
Oh, now I see what you were asking ..... lolOH! Like this!
Gear times OD ratio for final drive feel of.....
4.88 X .78 = 3.80 / now by .73 = 3.56 / now by .71 = 3.46
4.56 X .73 = 3.32
4.10 X .73 = 2.99
thanks AJ!
This would be the truck version correct?But I found a second ratio in the A833 with a .71od; unfortunately it has only 18 teeth on it, and it likes to split into tiny pieces when it gives up.
