I do believe if someone took a stock computer controlled 46RE that was shifting at 4500 rpm, or when it felt like it (as they seem to do) and swapped in a built 727 with a manual valve body, the results would be surprising. 
If the shift rpm is all that's holding you back I wouldn't be giving all the credit to a 727 if you shifted it higher and went quicker. Why can't you shift your 46RE manually if you need higher shift points?
As for the 1 1/2 second claims by SMR....I've dealt with SMR in the past. In my (lengthy and very expensive) experience, there is certainly no lack of BS from that operation!

I never said my 46RE was stock, and I never said it was holding me back.
I said...I'm going with a 727 because it's lighter and a three speed. I don't need/use/want an OD so why tow one down the 1/4 mile.

Do I detect just a hint of sarcasm? 
Nope.. no sarcasm... I REALLY want to know if there is a drastic difference... I'm looking for an OD unit to run in my car and if the performance is down a full second.. Then I'd probably stay away from the 500/518

Still waiting on my CRT tranmission, John's having back problems, so his time to build transmissions is limited. Having been there myself, he can take all the time he wants.
One thing I might point out...I'm breaking the golden rule of "one mod at a time". When I hit the track again, it will be with a Detroit Locker (replacing my toasted peg leg Auburn LSD), Monoleafs and Caltracs...A 3800-4000 stall converter (was 2800), and a new tune on my PCM.
That and no AC/Heater....The list goes on.

Well, so much for the trans vs. trans test...

I know, I figured since it was apart, why not do everything else. Even got my headers re-coated, that alone HAS got to be good for a tenth.

I dont know about overall E.T, but the A518 will give you a better 60 foot time due to the lower gear ratio in the planetary gear set! I think the A518 has a 2.74 low gear where the 727 is either a 2.45 or 2.54...cant remember!

I can't tell you any ET gain or loss, but I just wanted to say that Griner makes a fully manual valvebody for the 500/518s. You actually make the 3rd to OD shift with the shifter. 
This is exactly what I want.
It eludes me as to how you would be able to shift into overdrive with a shifter though. Overdrive is activated with a solenoid. Is it a button on the shifter?
As far as I know, the only way to do this and still have overdrive and lockup is with vac/pressure switches.
Details???

Maybe it's a custom made valve body and not a modified stock one ?
And where are the apples to oranges result of the swap ???

Old thread....
With the 727 and 4K converter I picked up 5 tenths on my 60 foot times...I easily picked up 8 tenths on my 1/4 mile times, but I was falling flat on my nose. Now with a better cam designed for my heads, a 4bbl M1 and 58mm TB, it's running high 12's, was runnning low 14's to 13.8.
That was well worth the wait.. Thanks for sharing the results..

Was that 5 tenths along with other changes? How much do you think the Caltracs played into that pick up on your 60 ft?
I can see where there is a lot of rotating mass removed , the power goes straight thru the OD section but it does spin all that weight and the slight drag of the OD clutches .
I'd say the 5 tenths was due to the 4k converter and 727. I wish I would have run it a few times with out the Monos and Caltracs. But I never spun with the built 46RE and 2800 converter, so I can't say I picked up any in the traction department.
But....trying to make ths clear, I bet the 727 & 4K stall would have taxed the non monoleaf/caltrac set up I ran with the 46RE.
