Switching from 4l80 to 4l60......
Switching from 4l80 to 4l60...... Building a '72 Blazer with a LQ4, and I have the 4l80e that came with it. I'm wanting to do a cam swap on the 6.0, but will need a stall to make it worth while. Problem is stalls for 4l80e's are expensive! However, the 4l60e's and stalls are reasonably priced. So, would it be a dumb idea to switch to the 4l60e since I can get one for less than the 4l80e stall alone? The Blazer will be a street/show car only and won't see a drag strip. Any opinions?
As long as it's a street driven show car, I don't see the problem with it. I would imagine those 72's aren't quite as heavy, especially with the top off.
What size tires are going on it?

Where have you seen a 4l80e stall for $500? Link?

Def keep the 80e. That would be a big step backwards to go get a 60e. Not to mention you'd have the re-flash the ecm for a 60e and also the wiring would be a bit different. FWIW my single disk billet PTC converter (lockup too) was $650 ~ 700 shipped. Not sure that a 60 converter is that much cheaper to justify having to buy a new trans that is weak from the get go.

I would not go to the 4L60e unless it was rebuilt with some stronger parts (Sun Shell, Disk, band and sprag at a min). OEM Sun Shell are pretty weak/thin and tend to strip out. The 4L65e or 70 is a better choice.

How big are the tires going to be on that blazer? Your probably already toward the heavier end of vehicles with the blazer, if you have oversize tires its going to be that much more stress on the 60e. I seem to notice that the completely stock 60e`s hold up ok, but it seems like I always hear about 60e failures and then the next thing is that they had a stall in front of it. Seems to me that the added stress of a high stall converter usually shortens the 60e`s life, especially in a heavy vehicle, or car that can hook up.
I guess I should have mentioned that it's a 2wd Blazer, but anyway.... I think I will just stick with the 4l80e since I have now seen converters around the $500 range. The ones I was seeing when I first looked were triple disc and they were in the $1100 range (FTI, RevMax, Circle D ect.) So my next question is, what brand has the best reputation? I was thinking Circle D since I haven't found much bad about them. Anyone have any experiences with any other brands?
