I'm considering stuffing my Cuda with a 4l80e and wondering if anyone else here has done it already
with a 2.94 first gear and a .74 6th gear, the possibilities seem endless on how well it can work
plus I can swap between a gen 3 hemi and my BB with a simple bell change if I wanted too

6th gear? You mean 4th? Or is there some aftermarket version of this transmission that has more gears?
Only 4L80e I had was in my 2500HD truck...it was flawless for 150k miles.
I wouldn't use a 4L60e behind anything making decent power. I've blown up 4 of them behind some pretty mild GM LS motors.

The 4L80e is basically a big electronic 4 speed overdrive TH400. The 4L60e is comparable to the TH350.
The 4L80e is a good trans for what you want to do, it's just physically big.

I went with the 518 trans.. basically its a 727 with OD and lock up.. I eliminated the lock up so I could run a high stall regular 727 conv... the 518 has a .69 OD ratio.... and the good thing.. it bolts right up to a small block... they are a heavy trans and its longer than the 727 with the OD in the tail shaft.. if you get one of the earlier ones all you need is a switch to turn on the OD or the lock up if you wanted to keep that... the reason I dumped the lock up is due to the conv.. you cant get a high stall that will have lock up and live(lack of clutch area in the conv)

Will a 727 converter work in the 518 trans? Wondering if I had a 518 w/ an UltraBell on it to fit behind my hemi, could I use my current converter in it? What year 518s only need the switch to turn the OD on? Stupid question...the 518 doesn't need a computer to run it? Sorry for the hijack Ray.

No... the standard 727 and the 518 type pumps use
a different drive lug set up... if you change the
input shaft and the pump you can use the 727 conv
BUT you loose the lock up when doing this(the pump
and conv for a 518 have oil paths that turn on the
clutch in the conv to have lock up)... there are 2
versions of 518... the late 80s has a single wire plug
and the early 90s has a 3 wire plug to control the
OD and or lock up... the single wire is what you
really want because it was a OD ONLY(no lock up) and
the 3 wire has both the OD and lock up but if you want
a high stall you nee to change the pump... if you
find a 518 that has the 7 pin connector that HAS to
use a trans controller(computer controller)... the
1 pin and 3 pin versions are what they call the "H"
version.. thats a hyd operated set up.. the 7 pin
is called a "E" version(electronic controlled)

Thats not entirely true - there is a 3 pin 518 that uses a 727 converter ( it's a non lockup version ) and I have it bolted up to an early hemi. I didnt want the lockup or the different converter and this was my best option.
They are hard to find, I forget the specifics , but i found one locally as a core.

I'm such a retard!!! It's a 2 pin.... there are 2 pin and 3 pins - the 3 pin ones have lockup. My apologies. I have a 2 PIN - NOT 3 pin - these use the 727 converters and do not have lockup.
