I'm in the process of switching from a M6 to a T400, and after talking to 5 other quality converter mfrs, I decided to go with Circle D. If this thing works half as good as it looks I will be pleased, the CNC work is beautiful The converter is 45-4800 stall and is only 230mm, slightly over 9" in diameter. Chris built it obviouly to fit a T400, but the front part was built to fit a LS1 OEM/aftermarket flexplate without using any adapter. Anyone interested in a converter ought to talk to him.

Sounds like the same verter i just put in my 4l60.I had the car re dynoed last week because i had the fast intake ported,and the tuner said it flashes to 47-4800 and felt nice and tight on the three pulles he made.I elected to have them leave out the lockup feature on mine ,he said it saves 4-5 pounds off the verter.Im trying to run 10.20 this year and i think just the verter change is gonna get me there.Good luck with your ride!!

Yes we do. Sounds like it has the normal 350/400 bolt pattern. What we do for our converter is use an extended pilot so there is no need for the spacer.
