Quest for the best milage from a C-10

[diggertodd]

Ready to start a new project - to outfit the highway hot rod with a new engine for the ultimate milage. I currently have a TCI 4L60E trans installed with a mostly stock 355 with edelbrock carb intake and headers. Tweaking and tuning has my besy highway at 14.1 mpg. I travel lots of miles on business and my wife and business partner would like to see fewer gas recepts.

No V6 or diesel - have my hot rod pride

My thoughts are a late model 305 roller cam block with small runner aluminum heads and the new Comp Cams/FAST elecronic fuel injection unit that bolts on like a carb with no manifold modifications. Have lots of friends at Comp for actual cam specs.

Any other suggestions?????

My engine builder for my dragster thinks a 383 combo would actually do better if I control the shifts lower with the 4L60E and will push the brick down the highway better

Any other suggestions?????
