With the carb reinstalled this time I've been able to balance all barrel to identical smooth airflow reading. Only remaining issue is #8 barrel makes a whistling noise that sounds like an open vacuum cap. When the uni-sync guage in placed on the velocity stack it mutes the sound. Since only this barrel makes this noise, I think there is still something minor going on.
You might be able to hear it in this video:

Is the hub circle size the same as the stock 88? The reason I am asking is I would like to use my current wheels which have the 57.1 mm hub centering circle and the 5x100 bolt pattern Could a 5x100 bolt pattern be drilled on the caddy hub flange? I am desperate to do this mod if possible as my stock hub is getting noisy
I have to order and pre pay for the caddy hubs so I would really appreciate it if you could measure the hub and let me know, thanks!

Per the timken website/catalog: 79-85 FWD (rear bearing) 513010: Wheel pilot diameter = 2.76" Fiero rear wheel bearing 513011k: Wheel pilot diameter = 2.25"

Thanks! So it looks like I am out of luck using my current wheels

Sorry Erik I missed your post but yes guru is right the hubs are bigger along with the bolt pattern.

you have a small blockage on the idle air port a good run will clear it nothing to worry about

No problem. Do you think the hub pilots have enough thickness to be machined down to 2.25?

Do your wheels have a removable concentric ring? All my aftermarket rims came with them, so when I swap hubs, I just swap out the concentric ring on the wheel.

Yes it just needed a bench tune as you said - another + for bubbajoe

Ok I'll move on to other stuff and keep an eye on it after some use

I'd say not a 1/2" look at the picture:
Last night I was working on the stainless rad hoses: There is a local hydralic hose place that I going to have the one end resealed on both hoses now that I've cut them to proper length:
Routing with look something like this:
This is the highest point in the system their was no fluid in the hard crossover pipe - a little concerning? Since the other hose connects to the bottom of the passenger rad I drained the DEXCOOL from the system in preparation for the swap.
