Anyone want to recommend the "best" holley tuning guide/book? I'm looking to really get into some fine tuning and i'd really like to get some good information. I know David Vizard has a book, any opinions on it? Any real good online tuning guides?

Vizard's Super Tune and Modify book is a hard one to beat as far as understanding carbs - the bulk of it's information is around Holley units.
David Vizard's book is a real good one that gives you a lot of good information but below is a couple of books you would want to get as well and the biggest thing is to understand how a carburetor works on everything on it such how it meters fuel and what the different circuit does function wise on a carburetor and also look up information on tuning a carburetor. All of those books won't give you everything but helps you to go in the right direction but over time doing research on carburetor trouble shooting and reading up on peoples tuning problems will give you a ton of information on tuning a carburetor.
Also there is a sticky about tuning a Holley 670 Street avenger on this forum as well and read up on it and it will give you some information as well and give you a more enhanced idea on how to tune a Holley style carburetor.
I listed some books on the Holley style but one for a Qjet as well in case you want to learn about it.

I have those three books you posted plus I think about four others and I think in all I have like over ten books or so that covers the old Demon carburetors and also all things Holley. I also have notes written down of what many carbs are calibrated out of the box from as much as information I can get from air bleeds and idle feed restrictors in the metering blocks and jetting etc to know how they are setup and am able to help folks when they might post and I can hopefully help them with a starting point to tune wise.
It comes in handy to compare. I over the years have come up with a generic starting range for tuning and setting up a Holley style carb for small blocks with bone stock to slightly wild camshaft size ranges and get within a good starting point and then not have to change a whole lot of things a bunch of times in order to get a good tune. But it always varies though from build to build.

I got into tuning the 4150 recently myself and I have the Vizard book. It's packed full of information yet, it's written from more of a theory standpoint than a DO X, Y, Z. I didn't feel that it was ultra helpful in helping me understand where to start or what to do...but I'm admittedly a moron with a lot of this stuff.
You're going to want an AFR gauge.

That is why it pays to get more then one book on tuning a Holley carb and also getting a book that shows you have to rebuild one etc. There is also some good videos on ytube if you look good enough but some times you have to be careful as some folks will recommended some old time myths on tuning a Holley and say you should do this or that because it worked for me.
That is where you want to learn how each system of the carburetors works and also how to learn on what first steps you need to take. Its not hard once you get a good understanding on how they function and transition from each circuit.

I remembered I also have this book:
Holly Carburetor Handbook 4150 & 4160 Hp473: Urich, Mike: 0075478003037: Amazon.com: Books
I think it's more of a no-frills, no-BS, to the point sort of book where the Vizard book gets more into a lot of theory and such that may not be helpful to someone really just trying to understand how the carb works and what they need to do to it to get it to run decent.
