as an owner of a 70GTQ DUAL BB, i wanted to build my car as a high 9's car that can still be street driven and a 70GTQ Dual BB i can honsetly say it has great street manors and spools up almost instantly, i do have a 9" non-lock-up at 3200. a 76-turbo will have a lot of lag, remember you said street driven.
trust me you'll have more than enough power from it, I'm not as experienced as some of these guys are, trust me i asked guys here also before i purchased mine, the 70gtq dual bb spools up great.
I say this turbo is definetly a part of the big picture, but you gotta have all the other parts line'd up in order to get a 9' sec pass. I know you have a roller cam, rockers, iron heads (ported i take ) but do you have the right injectors? remember fuel delivery twin in tank fuel pumps, headers and so on. what you want is kinda like what i wanted, but truth be told i may see the track maybe 3-4 times a yr. ( how about you ?) the guys have given alot of good advice but i guess it comes down to how much have you got to spend ( cause a new turbo is expensive ). good luck the purchase :smile:
ohh btw here's a pic of my 70gtq
