I have

You are talking about welding the undercut --right? I welded some a year or so ago--ran one in my car all last year--Probably 45-50 bottom 10 passes (was not dual feeding). Going to dual feed this year so I now have your billet shaft. I would guess strenght wise somewhere between stock and billet. That was locking the convertor @ the top of 3rd. Don't know if that would matter or not.
 
Chris i have 3 of these that are welded and cryoed. I dont have the balls to test one behind anything i own though. Let me know if you want one to thrash on.
 
I have used at least 4 of them before the billet ones came on the market. One in particular is behind a healthy big block that was in an 81 Camaro with an 85 CR trans that had a Red band and GN servo, hardened stator shaft and hardened sun shell as the only upgrades parts-wise. Trans is still working in a 72 truck with the same engine. By healthy, I don't mean a 13.00:1 engine. Just a 10.50:1, head porting, 280 duration or so cam, headers, 2800 stall, 850 carb. Don't know if he locks the converter other than overdrive position on the highway.

Mike Kurtz at Century Trans, used to tig them that way. They still twisted the splines tho. He uses the billet ones now. But in the past Mike either welded them or had them welded. But, again, like the hardened ones from Carr, they did not cure the problem.
