Picking a gear ratio

[Bleuii]

I did search first but I haven't found a definitive answer. Well I have a 2001 silverado rcsb with a 4.8 automatic. It currently has 3.42 gears. What I want to know is, what would be a good dd gear for that motor but also for a 6.0?

Need to know a little more, tire size, transmission, what kind of driving you do is all a good start to giving you an answer.

Sorry right now it is running a 245/70/17. It has a 4l65e, mainly in town city driving every now and again it sees highway.

2wd? 4.30s :imo:

 

[CammedVmax]

I'd say at least 4.10s but 4.30s is what I would put in it. If you were doing more highway I'd say 3.73. That's a 30.5" tire.

I want 4.10's in mine

 

[Bleuii]

Yes it is 2wd

 

[Fiesty]

4:10 is biggest I'd do with those dinky tires

 

[TheBrettster]

4.10s for grunt 3.73 for top end

 

[Ginger]

you swap trans?

4l60e is what comes stock in it.

 

[Samuel6731]

4:10s.

It wont kill top end. Itll make the "feel" of power come on alot earlier.

another though is just slapping in a stall converter.

4:10's

 

[Bleuii]

The previous owner swapped it. It has the tb stall.

that trans what maybe 2100rpm highway speed? when that trans blows up youll probably pull more rpm with an 80e.


i always use this for a better idea:

that gear engine makes 0 sense

Makes sense to me :shrug:

 

[Silver04]

I did 4.30s with 3k stall no complaints here.

If both engines are stock and will remain so then 4.30s if you're looking to swap in an cam/head/ exhaust 6.0 then 3.73 or 4.10 depending on cam size IMO
