Ray,
I think there are a couple of our cars with FI, but I haven't seen them personally. There are several systems available - I think that there's a recent thread on Club Cobra discussing them.
As with most things you get what you pay for, and most require some tweaking to get just right - especially if your engine is modified. The cheapest system will probably be $500 more than a single 4bbl carb. We tend to stay with the simplest system possible - we don't even use a choke. With the right technique the car still starts instantly, but may require a minute or two of idle time before smooth drive-off.
Having had cars with both engine compartment and underdash fuseboxes, I much prefer not having to crawl underneath the dash. I'm not as limber as I used to be.
There are circuit breakers that will fit in the AGC fuse mount, if that will help!
