Exactly why I didn't!!!!

Most welders prefer acetone for cleaning before welding. That's what I use now.

The tires I placed on order over 6 months ago finally came off of backorder. The G70-15's were my first choice over the L60's. I always kinda felt the L60's look like 10lb's of sh!t in a 5lb bag.

So, I got those mounted and balanced.





Back to the distributor conversation. I had installed the 170 distributor with 38 degrees total advance. Honestly, it seemed kinda soggy even after a bunch of fiddling. For grins, I put the Roto-Faze back in with the advance curve locked. In hindsight, I can see why it was locked from the get go. It starts better, the starter does not seem to mind it, and overall crisper. In hindsight, I am not surprised. The ZL1 cam is an antique, and probably does not have a ton of cylinder pressure while cranking.

After getting the ignition to where it's at, I still had some dripping fuel from the primary boosters as idle. I fiddled with the secondary throttle blade adjustment and that allowed me to close the primary throttle blades some more. That, included with lowering the primary float level 1/4 turn solved the dripping boosters. It also in turn, allowed me to idle the car down to 1000 rpm and the primary mixture screws proved to be a bit more responsive. I settled on an idle at 1150 rpm as it seems a little stable.


You could say I put the "goon tune" on the car now that the exhaust is installed. I suppose the car is finished for the most part, til the weather breaks in spring and I can road test

The sound quality is kinda crappy as I used my phone for this.

Car looks killer with the new shoes.

Do you have enough Vac to operate the Power Brakes>?
curious Vac at Idle.

Sound Great, Loved seeing the Car at MCACN was it 2011, 2016 or 2019 I am sure it was one of these.

If I raise the idle to 1250-1300, then it's plenty. Below that, I can run the booster out.

MCACN 2016 is when the car was there

I have the back seat out today, in order to address the rear window regulators. They always had been very tight and wanted to get them to operate like they should.

The question I have, revolves around a floor plug below the back seat. It looks as though it was never there. Is that uncommon? Perhaps taken out (or pushed out before)?

I know when Corey had the car, he replaced the rear package tray along with the trunk divider. Hence, this has been apart before. I'd be curious to see what some of you have observed. It looks as though it always was that way and I'd leave well enough alone then.

Usually the epoxy goes with the put but it would have left a mark where it was. I'd agree.. Never there so leave it that way.
