i was wondering how much horse hp con an 4l60e handle...i was want to take my 5.3 out n put an 6l n bolts on n tune n an cam an a 150 shot of go go juice

 

sounds like a ticking time bomb to me...mine doing ok(knock on wood) with just cam boltons and tune. but the torque from the 6l and spray sounds like a killer. do a search, read some horror stories

 

Gonna move this one over to the GM Drivetrain and Suspension section where it belongs, never seen a 4L60E stuffed internally into an engine yet...

 

I know the 4l65 is rated at 380 lbs tq....so less than that.

 

lol, that trans will last forever with that combo! They are pretty much indestructible.










J/k, I wouldn't run much more than a stock 6.0l with that trans. And also, I saw in one of your other threads you found a 6.0 for $3200? Please tell me you aren't going to pay that much. They can be had with 70-80k miles for $800, or 30-50k miles for 1k-1200 fairly easily. Don't be afraid of 70k miles, that is barely broken in yet.

 

no where i live has an 6.0...either someone done took it or they just dont have one,they dont keep the, long..but 3200 is brand new at the part store

 

a 4l60e con handle nothing

 

Try Car-Part.com, they have the inventory of most all junkyards that keep a computerized inventory.

 

Ouch, painful reading there. The 4L60E is not good for long with much more than stock power. I've heard of guys twisting output shafts off in a matter of days. I've been lucky so far with mine, but don't trust it.

 

how bout 4l80e?
