Not perfect, but good enough for today.
I also blended "VBI" so it looks like it belongs.
Just need to make butterflies on wire EDM, and buy the police injectors and a new adjustable regulator.

Thanks to @1987 GMC Jimmy for reminding me, i can modify the factory pressure regulator and emulate the same affect as the 65psi police injectors.
Im going to proceed with that tomorrow, order a new gasket set, make a spacer for the larger butterflies, and then should i have time, install, and see how she roars.

Other than losing my adjustable regulator setup after spraying my own eye with carb cleaner, and waiting on the gasket set i ordered... the 650cfm VBI is ready to transplant on.
