Don, I was interested in your mention of 25 mpg with the 600 carb. I have not followed your build very well so can you recap the driveline that gave you 25 mpg? Admittedly the light weight of the car helps a lot but can you review the specs of the car such as:

1. rear gear ratio
2. cu. in. of engine
3. cam specs
4. tranmission
