Edelbrock 1405 rebuild ?
 

I rebuilt my carb with edel 1477 kit. It says that the float drop should be 15/16". After further investigation, I found a tuning guide which said 1-1/4 +/- 1/4". Can someone please tell me the proper float drop? It is on a 79 150 4x4 with a 460 .060 over.

7/16 level with a 15/16 drop according to the manual page 14

Yes, I do agree with that. I am just thrown off with page 10 of this. http://www.edelbrock.com/automotive_...ers_manual.pdf

I'm in the process of rebuilding my 1403 and the sheet says 15/16" too. Interestingly enough, it seems to have come from the factory with a drop of almost 2 inches, which is so large that the floats would just ride the bottom of the bowl until the needle cuts off. I'm just going to set mine to what the sheet says - 15/16". I have a tuning booklet that came with the carburetor and it says 15/16" as well.
