Can't decide auto or manual?

I know I'm going to go with a 5.7 and then later on a stroker or 6.1 hemi. But I'm buildin the car for pro touring and was going to use a 545rfe auto so my wife could drive it. She's now said she won't drive the car as she is scared she'll break it or worse. LOL

So not I've been pondering a manual trans. I'd love a T56 but have to settle for a Keisler TKO or RS600 package since it's easier for me. Sourcing parts for the restoration is taxing enough.

So anyone have an opinion of the T56 and costs and such? How does it compair to a Keisler setup?
