One more thing on the magnums.

It would be really cool if someone with some good fab skills would take and put the injectors (accel cone spray petter ones) all on one rail inside the beer barrel pointing each one directly at the entrance of the port. This would give more time for the fuel to vaporize before going in the chamber. That is one reason EFI in general don't get better mpg.

I know all these things I talk about are not worth much all by there selves but when you get a whole bunch of things working together you can see some big saveings.
