thought I would update this instead of starting over.
I revamped the top plenum for the 3rd time, and its stays now.. I got my engine rebuilt over winter and got it back end of may. First car show was June so I did a mad panic to get it all together after a long winter thrash.
I have been driving the car constantly since June 2nd, about 4 times a week, and its running flawlessly every time. Car runs and drives awesome, no hesitation on the tunnel ram, instant pedal.. The Fast efi is learning all the time, and works perfect. I have close to 700 miles on the car now,, and have never once left stranded. I am very impressed and happy with the engine and efi.
