Re: 57 Chevy Wagon - Californa Dreamin'

We took a 550 mile road trip to visit some friends and attend a cruise over the weekend. The rear axle problem appears to be 99% contained. I had one small spot on the backside of the rim that looked like a few drops of axle lube may have dripped onto it, but other than that, no signs of major trouble. I've added a new seal to my winter makeover list.

Speaking of that, my list now includes:
1. Replace the 3000-3200 rpm stall converter with one closer to stock - like a 1600-2000 unit.
2. Take another stab at the EFI using my intake setup and Holley's Terminator X controller.
3. Replace the dual Perma Cool fans with Spal fans that actually move air.
4. Repair a small spot on the roof that's lifting due to my improper prep.

There's certain to be more, but those are the biggies. We have a few more cruise-in's and car shows to attend before the car gets blown apart for repairs, so meanwhile, I decided to test another linkage setup on the dual quads. Ever since I put the carbs on, I've been using a progressive linkage that mainly runs off the rear carb. In fact, the front carb has the idle mixture screws all the way in and the primary throttle blades completely closed until the rear carb reaches half throttle. So most low speed operation is handled by the rear carb only. The AFR and the plugs are white when comin in off the highway but in town, the center plugs appear slightly darker which is probably due to the dual plane intake.

So I decided to do something I've been wanting to try and that's to use a direct link between the carbs. I reset the idle mixture screws on the front carb and tweaked the curb idle. It feels more responsive and the AFR readings are much more stable. I'm going to leave it like this for awhile and see how it affects the mileage. On our trip this weekend, we averaged 15.2 mpg which was the same as the trip to Bowling Green. So that should be a good baseline. We have one more long trip planned which will give me a chance to compare.
