I need a 2200-2500 stall converter for my truck and it has the 80e tranny. I know that alot of guys run the I6 TB stall with the 60s. I was doing some research and found that the 80e was behind a 4.3 V6 in a 2500/3500 van and they stalled the highest of the different motors they have been behind. What I am asking, is with the added weight and the torque of my truck would that converter be in the range of where I want to be and would I still be able to tow with it? I don't see much since in paying 900 for a converter that is only a couple RPMs over stock if the stock stalls close to 2000. I was looking at TCI but since they don't give the stall of each TC and just the increase over stock I am not sure exactly what I need. I am also afraid that the stall they are advertising wasn't in a vehicled that weighs as much as mine. Any help is greatly appreciated I am trying to sort everything out now and get all the parts together for my motor swap. Thanks

 

My stock 80 converter is from a 250HD. It stalls to 2500 RPM behind a 6L without boost.

 

So I don't need to change mine? I have a 1500 HD with a 4L80E. What is yours in?

 

A reg cab. If you feel that your current converter is too tight I think you will need a 2800+. Next time you drive the truck stand on the brakes and see what you can get it to stall to. You should see at least 2200 rpm.

 

Well, I am building a motor now and the cam I have it was recommended that I run a 2500 stall converter. So that is why I was wanting to change

 

This is a 1500HD with catback and tune only on a stock 80 stall. With more power, it should stall a little higher.

 

I guess I will see how mine does then. My motor should make 475+/- so maybe it will stall where I want

 

You are going to want some more stall. With the 4.3 4l80e TC, you will be able to tow whatever you want to. Its still a stock TC.

Look into Edge converters. Seem to be quality individually built for your application and at some VERY good prices. I was gona go with a stock converter in my 80e till I found them. I'm like you and didn't want to pay 900-1000 for a damn converter. He recommended a "street edge" for me and will custom build it to for what ever I want even to fit my LS1 flex plate and crank hub. I think you would probable want the "mild street edge". He told me my truck will retain 100% street manners and can still tow just fine with them. He also told me that with his lock up clutch i could lock it up under WOT and it would probable brake the input shaft before the clutch slipped, lol. He said his "high carbon" lock up clutches are 140% stronger then 3 disk Kevlar.

 

I would try your stock converter out. The one in my 03 1500HD would brake stall to 2500 RPM when it was stock with a Superchips tune. Now with the STS turbo at 12 psi it will stall a little over 3000 rpm on the stock engine. I have not tried it yet on the new engine.
