1955 Chevy 3100 Pro Touring Project

Well as I continue to start ordering parts today I did make some big head way. Met with my motor builder, we came to an agreeance to build a new ls3, going to convert it to the Holley hp efi system, 95mm throttle body, 225/235 @.05 cam , valve springs and some engine dress up items. My next decision is what trans I want to run. Can anybody give me there opinion between a T56 or a 4l70e.

Thanks
Jacob
