The have a 69 convertible that they built in 1999 that runs a SB2 motor. They took it on a couple of power tours.
The way I understand it is the best way to make those motors streetable is to make a stroker motor. Jimmy Johnson's 67 camaro is running an SB2 motor. They are taking a cup motor and lowering the compression and stroking it out to 400+ inches.
www.racingjunk.com is a good site for that kind of stuff. Another good option if you are looking for that style of motor is an 18 degree 9:1 busch motor.
I have a friend that has one for sale complete from oil pan to carb with a 5 stage dry sump. Kinsler individual runner intake and 2 new turbos.
