Turbo change

I would agree on the .82 ar t4 turbine housing for that Gt35 configuration…if you can find it. I still think the 30series is too small even if you went t3(I ran a 3076 @ 150ci). They do make t4->t3 adapters.

At what rpm are you seeing full boost now?

Im very curious to see how the super sniper does with your setup. I’ve been tuning my buddies 454/F1 combo and it’s been a real pleasure vs carb tuning. I hope you plan to take advantage of timing control.
My timing is run by MSD 6530. Don’t plan on changing that. I have boost maps and two step set up thru it. I’m leaning towards the gt35 but not in a major rush so going to do more research. I do appreciate everyone’s time and energy helping with this.
