gears/top speed

[nothingface5384]

hi there i'm still curious on gear/tire combos and the top highway speed

my truck will weigh around 3450 pounds w/ the buick 4.1/ th350 combo
i'll most likely either be running 37x 12.5 16 trxus ssrs
i would like to beable to top out atleast 65 70mph

rpms at 60 with 4.88s would be 2730rpm
with 35s the rpms would be 2886

if i go 4.56
37s 2551 rpm
35s 2697

i just dont want my pickup turning out like my buddies 80s silverado...he has a 350 4speed manual running 4.11s w/ 38x1150 and he tops out at about 50mph on the highway

this will be a dd /weekend warroir
thanks for the pm fourwd1for narrowing down my choices
just wanna know what every one else would think

If it were me. I would do what ever it is that fourwd1 suggested to do in his PM. The guy def knows how to set up the right combos on yotas.
