While we were doing this upgrade someone asked, "Why do the drop spindles when your car is already low?" The answer is that we did it precisely because the car was low. In other words, with our '68 at its best stance, the control arm angles were all wonky, and to get the control arms parallel to the ground, the front of our car would end up sitting like a 4x4.
The 1.25-inch drop of the Raceseng uprights let us have our stance and proper suspension geometry. We also gained some needed front shock travel.
Easy Breathing
Engine breather systems are often overlooked by builders, and we're no exception. When we originally built our car, we slapped a couple filters on the valve covers and called it good. It was fine for the street, and even for the occasional autocross, but once we hit the road course, and started performing sustained 1.3g gyrations, it proved woefully inadequate. What we needed was a proper system, so we came up with a plan and headed to Pozzi Racing to make it happen.

We would be running our breather off the oil fill port of our valve cover, the same place we had stuck our filter before. But in order help keep oil in the engine, we fashioned a baffle and welded it in place. It was simple to do, and it will make it harder for oil to make an unwanted exit.
If any oil did make it past...
If any oil did make it past the baffle, our plan was to catch it in a small tank. Unfortunately we couldn't find one small enough to mount where we wanted. The solution was to pick up a catch can from Allstar Performance and make a few modifications. The tank is the perfect diameter, but it's a bit too long. By taking the material out of the bottom of the Allstar tank, we retained all of its internal baffling.

We simply cut off the very bottom of the tank, removed a few inches, and then welded the bottom back on. This was way easier than trying to fabricate a tank from scratch. We then welded on a 6-AN fitting to the tank.

The plan was to mount the tank to the front of the passenger side head. Fortunately, we had a couple decorative head plates lying around. These were designed to bolt to the front of an LS-type head and turned out to be perfect for a sweet-looking tank mount. After test-fitting and finding all the right angles, Dave welded the shortened catch tank to the head plate.

After a trip to the powder painter, here is our finished product. This, combined with our valley cover being plumbed to our intake manifold, gives us plenty of crankcase ventilation and keeps the oil where it belongs: in the engine or at worse, in the catch tank.
