efi, not to speak for Jamie, but whatever you can buy for an 18-spline now will work with the new trans. To me, that's what makes this such a great product.

I had already talked to my son about the 18-spline overdrive that Jamie was already selling to replace the A-body 18-spline that I built for his car. This is even better, although a mild 440 with 3.23 gears in an a-body hardly needs that many forward gears..........

He may be in the market for one in the next couple of years, but I don't think I'll have another four speed car. My Barracuda is getting a 727 behind the 440 so that my wife can drive it and it is SOOOOOOOOOO much cheaper.
