Edelbrock EFI

[Mark Romans]

I average about 12.5mpg, but I didn't build it for fuel econ.  It will get
23-25 on hwy if I'm real mellow.  30% od helps.  I haven't tested it yet but
just put the hwy fuel to 16.0 to one from 15.5, have to hook up diacom and
check it out, might give me a bit better fuel econ yet!
