I'm going to agree with DaytonaTurbo about the wet manifold vs a port injection, the tbi setup I'm building I have no doubt will be more consistent in performance than the holleys that are currently on my car.
Starting has been an issue on a cold day or very hot one fuel would boil in the bowls.(I guess I should have known better than to use a tri power off a 68 vette.)

As far as Sliders Q, no mechanical problems are anticipated, my issues will be with fuel mapping and the spark curve. I will be asking for help when it's time to start mapping.

Here's a pic of the setup with the end tbi with pressure regulator and gauge installed.
will try to machine the top lead-in and air cleaner stud bosses next week.
