I just bought a 1977 F250 with a 400 eng, aut. transmission, cruise control, and a terrible mpg.
For better milage I'd like to upgrade to a new 4-bbl Edelbrock or Holley carb.
I understand that there is a tricky part with the kickdown, and I'm not able to do that job myself.
Any recomendation (hopefully between Seattle and Everett)for a place where they'll do a good job?
Any idea how much I'll have to spend?

Ardq.

 

There is really nothing tricky about it. Edelbrock sells the add on bracket for your kickdown lever. I have the same year truck and just did the conversion. Any auto repair shop should be able to handle the job. For the intake, carb and gaskets you will spend in the $500 range.Not to sure about the labor, but its only a 1.5 hr job.

 

Thanks.
How many miles did you gain after the conversion?

 

Not sure on that one as my conversion was done on a remanufactured 400 as soon as it was received. I am getting between 10 and 12 mpg.
