I just picked up a '77 Zink Z-10C for Auto-X duty, but the car hasn't been raced in eight years. I've obviously got some work ahead of me getting it ready for the spring, first of which will be replacing the fuel system. The car currently has a small (probably 1.5 gallon) aluminum fuel cell in the right sidepod, and the foam was a known problem before it was put up. Also, the previous owner ran 93 octane auto fuel, but I've seen a lot (most?) folks on here run 110 AV fuel. Here's my series of noobie questions:
- Where the heck can I get foam for an oddball little cell? Pegasus only seems to have larger size pieces.
- How much power is there typically to gain moving from 93 to 110?
- Assuming I could source the 110AV, what would I need to adapt the engine to running that? I'm assuming the carb settings would need to be adjusted to run a different octane, correct? As little as I know about FFs, I know even less about the dark art of adjusting carbs.
Thanks guys!
