I put my simple instructions on how to set the floats on the Edelbrock carburators on my webpage; http://www.robdiesel.com Also, I am changing the layout a wee bit so I am also asking that you compare the Edelbrock Floats page with the testpage I have linked too. The only difference is what side the thumbnails are, simple but important. Any and all comments and suggestions are welcome. Anyone else running the Edelbrock 600cfm on their 440? What do you think? I can't really say that either of mine are set just right, but the 600 gave a noticable improvement over the 750 I had on previously.
