How far to rev this 273 commando build

AJ/FormS said
With the 3.09 low, and on the street,I found the same thing 3.09x3.55=10.97 and 2.66x4.11=10.93; making them take off equally in first gear.
Where things change is on and after the 1-2 shift. On the street with a torquey engine, I found 4 gears didn't really benefit from deep rear gears, and I tried a lot of them, from 5.38s on down to 3.91s. Also tried less than 3.55s which turned out to be the best all-round with my GVOD, so they are stayin.
But I totally agree with; "I tried a 3.91 gear last summer and did not see any improvements just had to shift sooner and more frequent . put the 3.55 back in"

Thanks AJ !
I fired up the commando after 4 months of hibernation . Couple new changes coming. My flowmaster 40's are coming off and new dynomax ultra flows are going on this week. Also a new change to carburation.... off with the stock 500 cfm afb and on with a 600-625 avs stock to 340 dart/cuda and 383 RR. and see how that performs at a later date .
