Your best bet is to PM 346Duster(Chris Andrews Racing transmissions)and get some advise from him on your tranny build.I,ve found him to be very helpful and just an all around nice guy.
That's just the guy who was going to build it for me! His shop is about 30 minutes north of where I live and I have talked to him in person about it. All of the parts I listed in my first post were recommended by him and were laid out in a quote he wrote up for me. He recommended against a forward shift pattern and for a reverse-manual VB with low-band apply. I'm not concerned about shifting on the street because I wanted to convert it to a 4-speed anyway (plus my DD is stick-shift too). Really my main concern with a reverse shift pattern is the inability to shift into neutral for coasting but I have a feeling that's a bad idea in itself.
And before I forget again my 360 is going to be stock-stroke with mildly worked Magnum heads (normal replacement ones), around 10.5:1 comp, Lunati Voodoo 256/262 cam (with 1.6:1 Magnum rockers), RPM AirGap intake, and Doug's headers.
