doug nash 5-speed and a 5.3 ??????

[KSBRKTRACER]

Has anyone done this combo ...... I just traded for a doug nash street 5-speed that has been upgraded with a vasco-jet main shaft, I'm gonna put it behind a mild 454 for now but eventually I want to put it behind my 5.3 in my 67 camaro if possible........? Does the tunnel require any mods to run it behind the 454 ???? What have you done for a shifter ???? crossmember ????
