Single turbo on dual exhaust

don't worry Duster I'm not sure about any of this, even after reading countless articles and how to posts for the last 4 days I still have no clue. Basically I was thinking what your thinking but it seems like it should be easier some how.

B2B Basically this all started because I was about to buy a TQ-Cam-Carb-Head combo for the 318 I have in the car or the 360 I have sitting beside it. When I found out I could take the J heads off the 360 and put them on the 318 with bigger valves and then be rewarded for the low compression by turbocharging I jumped on board, I don't need 1000hp but 500 - 600 would be great (first hit free?). It has msd digital 6, 150 shot No2, a ld4b, afb, hookers & 904 w/ 2100 converter and stock gears, 27" x 9" rear 26" x 7" I'm thinking 2800 stall and 3.9 gears a Mighty demon BC 650, a (insert your recommendation) Turbo, Whatever cam comp cams tells me to get with this combo, stock bottom end and the J heads with 2.2 valves. But I just came up with this stupid idea so I'm not sure about anything. It's just a track toy and I haven't made it there yet so I'm not looking for a cage, loop, parachute wheelie machine
