Need turbo advice

engine specs

Its a 406. An early 70's 400 punched 30 over. I'm not sure about the cam, but it is quite lumpy. That can always be swapped. i have a performer rpm manifold with a 730cfm holley supercharger carb. However one day i want to go with EFI. The heads I believe are stock and are cast. I also want to swap for some trickflows or brodix eventually. The rods, pistons are forged. It has an HEI distributor. My tranny is a 700R4 with lock-up converter from a vette. The rear end is a 3:73 12-bolt posi. 1:6:1 Roller rockers will definately go on. What other components would you reccomend to make a turbo setup work best? ie. cam, valve size, rocker ratio...etc. I know I will probably need a cam with a wide LDA. Thanx. I really appreciate this.
