What gears

[mike205]

I have a 1989 chevy c1500
In the process of installing my 2008 ly6 with 4L80e Trans
Just bought a 12 bolt out of a1983 silverado and was gonna build it
Was wondering what y'all recommend for my gear ratio?
I'm doing a mild cam aswell 216 Intake 230 exhaust 600 lift
Keeping vvt. Also will be a DD

do you plan on doing anything else to the truck? ie boost/stall? id say 4:10 depends on stall and tire size? what gears are you running now?

[Frenchy]

4.56

[mike205]

Yeah I do have a stall
Yank 3200
No boost and maybe a bigger cam later on but for now just wanting to drive it
And tire size there 28 inches overall

Regular cab I'd say 373 for DD. depending on how far you drive maybe 411 for a lil more fun.

Ok thanks
I was thinking either 373 or 410

[darnie1987]

id still say 410. unless you do a grip of long distance driving. i had a 3200 stall with 373's and 33'' tires and i could fry them.

With 28" tires you could get away with 3.73 and still have it perform well. I run 4.10's with 30" tires and really like it.

At 70mph, you'll be spinning around 2350 rpm with 3.73's.

With 4.10's at 70mph, you'll be spinning around 2583 rpm.
