@Fuzz posted:Wow, this is great information, specifically because my mechanic is recommending the Holley Sniper EFI Self-tuning 550-510K. After reading what tberg wrote, I am not sure I want to throw away money like that. Which Edelbrock carb did you install?
If you are worried about money, then don't go with EFI. It will never pay for itself on a Pantera because it is doubtful that you will ever drive the car enough. The early aftermarket EFI systems did have problems and when they came out it was very new technology for the aftermarket. In recent years the systems have improved tremendously. There are lots of high horsepower muscle cars that are using aftermarket EFI systems and the owners seem to like them. There are also many more EFI tuners around that actually know how the systems work and can troubleshoot them if necessary. When my 390 cubic inch stroker engine was rebuilt, it was tuned on an engine dyno in 1000 rpm increments when it was hot and cold. I put the engine back in the car and hooked everything up and it runs great. It helps if you have someone that knows what they are doing. FAST makes a nice system monitor which I installed. It tells me everything that is going on with the engine in real time. It also has fault codes that will be displayed on the screen, so there is no need to hook up a laptop computer to find out what is happening.
