Stopped by the shop yesterday and was able to check out recent progress... exhaust is mostly complete, though I don’t like the way the tailpipes are routed, so we need to re-do those, which shouldn’t be a big deal. Here are some pictures I took of exhaust - I’m using 3 1/2” oval pipes (equivalent in flow to 3” round pipe) from headers through X-pipe to Spintech mufflers. The mufflers have oval inlets and round outlets, so easy transition to 3” round pipe from the muffler on back, since the round pipe is much easier to snake above rear suspension and around fuel tank.
Kurt modified the transmission cross member slightly. The change kept the transmission mount height exactly where it was, but elevated the sides of the mount about an inch, which gave us another inch or so clearance to tuck the oval tubing closer to the floor.
Transition from muffler to tailpipes are made with V-band clamps right off the muffler.
From there, exhaust snakes up and over axle and QuadraLink, and around fuel tank.
As I mentioned above, the tail pipes are tacked together and currently turn to the side and dump behind each rear wheel. I really don’t like this look, so we’re going to re-do this portion.
There is plenty of space to turn the tailpipes up and run them inside the rear quarter panels, above the pinch weld, so they can’t be seen from the side of the car. Below are some photos of what I have in mind from a nice ‘67 Chevy II exhaust project detailed on Steve’s nova site forum. Pipes will turn down and exit toward the ground near corners of rear bumper with everything up above the bottom edge of the rear quarter panel.
Guys have most of the brake lines finished up in the rear and working on running them to the master cylinder.
Got a nice picture of the wiring and plumbing for the Vaporworx PWM fuel pump controller while I was crawling around under the car
For fuel line, I ordered some carbon lined PTFE hose from TechAFX, which is available in a cool, matte black finish. The finish is similar to regular black radiator hose and will match the hoses I’m using throughout the engine compartment (radiator hoses, push-lock hoses for catch can and PCV system, etc). Below shows the hose connected to fuel rail.
I have a fuel pressure gauge set up in my Holley digital dash, so I needed a sending unit plumbed into the system. Wanted to measure pressure as close to the fuel rail as possible, but keep it hidden. We were originally thinking we would plumb it under the car near firewall; however, we were able to plumb the port for the sensor right off of the fuel rail itself, and have the sending unit and related wiring all fit under the fuel rail cover so it is completely out of sight.
We’ll get the tailpipes redone this week and Kurt is also going to modify the hood latch for a remote hood release. We’re following a mod done by some others over on Steve’s nova site. The hood latch mechanism has two releases - first, it releases the hood lock and then as you pull the lever further, it releases the safety latch. You can modify the latch so the lever behind the grill only releases the safety latch. You then fab a bracket and have the hood lock operated by a cable mounted under the dash. That way, unless you’ve first released the hood lock via the cable in the car, the lever behind the grill doesn’t do anything when you pull on it. Take care,
Brian
