Until you’ve owned and driven one, you don’t realize and appreciate how much the car is an instant carshow, no matter where you go. Stopping for gas is never a quick in and out. Everyone wants to admire and see more. To the average admirer, it’s the car and the craftsmanship. But to the gear head / hot-rodder, they want to see the engine. When you lift the hood, the original FE is an immediate attention getter – how’d you get all that to fit in there. But when it’s topped with an EightStack, whether Weber’s or the injected look-alikes, Oh, man, that’s beautiful. And the conversation continues from there.
The EightStack system has become immensely popular in the last few years. The system is very easy to live with, assuming you do your homework first. If you’re considering a system:
- Do you want Weber’s or an injected look-alike system.
- The Webers are the ultimate period correct system however they can be very tempermental. The Cobra’s typically used the 48IDA’s and they prefer to run at the full open mode. Idling wasn’t designed into them and it takes considerable work to get them to idle and transition smoothly
- Fuel injection is the modern day solution however it involves electronics and tuning to make it work. It is not Plug n’ Play. But once it’s setup properly, the consistent starting and fuel mileage is hard to beat
- Are you technically skilled to support the system? Once setup, they are pretty much trouble fee. But there is a fairly steep learning curve getting there. If you just want to bolt it on and go drive. I suggest you look elsewhere
- Are you prepared for the expense? Just the hardware will burn thru $5-8,000 real quick. Then you need tuning on top of that. Going with injection, you’ll need to add a few more thousand to cover the electronics. Then add installation labor and tuning, fuel system modification . . .
No, I’m not trying to talk you out of it, I just want you to be aware of the path you’re about to set out on. The excitement as you start and work on the project is only exceeded by the gratification when you drive and show the system.
The complete system requires a number of sub-assemblies, all must work with one another smoothly and accurately. We’ll break each one into smaller parts to make it a little easier to manage
