How would you address the emulsification issue? Would you go down one size across the board or can you change one or two at a time?
Kind of like the Remington 700 Triggers, they are actually great units but very easy to mis-adjust. so remington said explicitly; don't adjust them. Ended up costing Remington millions in claims paying the idiots who made them unsafe and hurt themselves or someone else.Interesting that Holley North America tells you to NOT touch the air bleeds, but Quick Fuel Australia encourages it. Go figure. I will say… that without a through understanding (and a lot of hands-on R&D) of emulsion circuits, Holley is probably right in discouraging the average grease monkey from doing that.
With a ‘moderate cam’ and those heads, that annular 650 is a great choice. As to ‘others to consider’, manual transmission/light car/stroker torque gives you a lot of options. Just know that about anything will take some work on your end to dial it in. I’ll post more later.I am looking at the QFT SS-650-AN. My questions is, is it enough carb to perform well at the topend? Any other carb I consider?
Thanks ArizonaGT. I realize that I will have to put some work into tuning the carburetor and I am looking forward to it. I need to find my spare wideband and install it in the car. The engine builder recommended a Holley 0-76750BK and some friends building a 302 for his Jaguar is looking at the new Edlebrock VRS 1450.With a ‘moderate cam’ and those heads, that annular 650 is a great choice.

Congrats on the Mustang 👍
That’s what we‘re for 👍I haven't. Is there some
idiotssmart consumer’s guide to the different types/models of carb? Holley's website it not very useful.
I don't mind spending a little bit more initially and getting a carb with a lot more tuning features. My current carb seems to have the butterflies quite a bit open to idle. The tuning articles that I've been reading say that's a big no-no. So, I think I might be helped with a carb having idle air bypass.That’s what we‘re for 👍
Brawler is the economy/entry-level line, they’re pretty good carburetors for the money. They will have fewer bells ‘n whistles compared to the XP and HP branded Holleys, but for most street cars they‘re a good value. Same for the Quick Fuel HR (hotrod) line; not as many features as the high end stuff but they are a good value for 99% of street motors. Proform also makes some good stuff for the money.
It pretty much depends on how deep you want to dive in. Most street motors are perfectly happy with little more than typical carb adjustments and maybe some re-jetting (for your altitude and weather), but if you want infinite tuning and calibration, entry level isn’t for you.
Just store them in the living room like everyone else.Here in Alabama we just can't show off like that . Get e'm all lined up then,
Come back in a day or so and the dirt daubers will have every cavity in those thing full of mud .
And if you think they will be safe stored in a cabinet ,better make sure all the openings in the cabinet are sealed. Because those things ain't afraid of the dark .
Your setup looks pretty. I want to put a fuel filter in line, in case there is crud in the tank. Do you put one before or after the fuel pump?
Primary jetting will land somewhere around 70, +/- a few sizes. If you want to block the secondary PV, add 8-10 sizes to the secondary side jetting. Nothing wrong with running a secondary PV but it depends on how hard your car accelerates. If it hooks well, you run the risk of uncovering the secondary PV and that can lean out WOT.Your setup looks pretty. I want to put a fuel filter in line, in case there is crud in the tank.

What all should I get to tune the carb?
Here is my list:
Set of smaller main jets (What sizes?)
Smaller size PVRs
Power valves that open later
Should I get larger air bleeds?
A set of nonstick gaskets.
