Whats your mpg?

This is mainly gear towards those with an early to mid 90's chevy/gmc 1/2 ton x-cab conversion but would be interested in others experiences.

Include the following in your post:

engine displacement ~ modifications (including exhaust)

transmission used (also modifications of)

rear axle ratio

If you have dyno information or track times, feel free to include that as well.

Thanks
