Hard to believe how clean that engine bay is, surely you don't drive it everyday in all kinds of weather.

Welcome to the forum!
 
Thanks! I only drive my car in the dry. Otherwise I'd spend a lifetime cleaning to keep it the way it is.

Very nice Danny. Welcome.
How does it run otherwise (ign stumble)?

Here is a tip: move your throttle return spring forward of the linkage.
That way the force of the return spring cancels out the force of the cable pulling on the throttle shaft.
In other words, equal and opposite forces.
That way you will not need to put throttle shaft bushings in to correct for a vacuum leak there in the near future.
 
Howdy. Does the FAST system have a logging feature? A common EFI symptom is the fuel delivery at transition. What we need to look at is if it is stumbling due to a lean or rich event.
I have a ‘68 Camaro and FiTech EFI.
Cheers
