Tuning the fuel system- Lemar Walden Automotive

I was wisely guided to Lamar Walden Automotive for advice on tuning my system. Lamar is famous for his high performance 409's but he can work on anything...even a Ford. During our discussion, Lamar suggested that I go back to the 650 CFM carb and wanted to address the carb angle. The carb in a Pantera actually leans forward due to the engine placement which makes it challenging to adjust the floats, etc. Because Lamar has a full machine shop, Lamar took off the intake and machined it so that the carb would sit flat. He also hot tanked the manifold and got it nice and clean. Now the Pantera is running just right without any flooding issues. We did have some issues with the idle, we looked for a vacuum leak and couldn't find one. It was also very cold and the car seems to idle OK now that it is warmer. Anyway, I was very happy with Lamar's service, prices and workmanship.

Final Alignment....more problems...

After I finished the fuel system, I brought my car back to Gran Turismo to get the final alignment. As you may have read before, everytime I take it to Gran Turismo East, I find something else wrong with the car. During this trip, I realized:
1.) Brakelight switch was out
2.) The carb I got was way too big for the motor and I was running way to rich

Well, at least I got the car aligned with no issues! Now to address more problems.

Fuel Lines & Pump

For this project, I wanted to replace all the fuel lines from the tank, to the pump and from the pump up to the carb. I also wanted to install a fuel pressure gauge and wrap the fuel lines in heat wrap to control any vapor lock. I also changed the glass fuel filter between the pump and the carb to a metal fuel filter.

While I was in the mix with the fuel lines, I thought I would change out the old fuel pump. The old pump was in good shape

My first replacement was a beautiful pump from RobbMc Performance. This pump is a work of art. Unfortunately, I couldn't get it to fit due to a clearance issue with the coolant line. Others suggested that I just relocate the line but I didn't want to deal with bleeding the cooling system, etc.

As a result, I went to a trusty holley fuel pump and it installed without issue.

Been a while...

You have probably noticed that I have been dark for some time. We decided to move back to New Jersey from Atlanta which has kept me busy. However, I have had some work done to the car. The Pantera is now in New Jersey in storage awaiting the purchas of our new house w/ garage of course! I'll do some quick updates.
