Help with picking out a carb for 5.9 magnum

ONLY ONE CARBURETOR!!!... LOL...
I've got two 625 Street demons on the duster... But I wouldn't recommend that..
I will be getting a 750 Street demon for my up coming small block truck build...
I have a costumer with a 750 street demon on a 400 GTO and it had the float bowls way out of adjustment out of the box... A simple adjustment and no problems.. actually it was good to take it apart as it gave him a greater understanding of how it works and how adjustments effect it.. also confidence to make adjustments...
Whatever carb you choose keep a log of factory settings and how it acted and every adjustment and how it acted and come back to this thread x-months from now and thank me you did...:thumbsup:...
Changing one thing at a time and keeping a log is a great idea. It's too easy to lose the rabbit when making lots of changes.
