you could do a (dreaded around here) draw thru system by using the 292 manifold. weld a short vertical pipe with turbo flange on top to the top of the flat front portion, (if its an early one) sorta above the ribbed portion, and cap the stock exhaust opening. Then plumb the intake by making some bracketry to attach the carb to the turbo, and let the pressured air/fuel side blow down into the intake by way of the stock intake carb inlet (or of course a Cliff or Offy manifold if they dont sick out away from the engine too far and cover up the exhaust manifold-the stock intake will work fine)
I have not read it in quite a while, but go to Tom Lowe's site and find the turbo article of how Dick Griffin did it to a 250 inch '66 Cutlass (102mph in the low 13's- high 12's).
The 292 exhaust has a better shape and it sticks out away from the stock intake to allow the aforementioned vertical pipe.
Only tight spot will be trying to route a 3" exaust out of the blower--but every thing has a prob or two.
