Yes, cam choice is going to be interesting, again trying to avoid the temptation to go too big.

Gottcha! thank you !! those phords.....
I haven't forgotten you asked. I haven't had a chance to get the picture yet. I will, I promise.
Have you had a chance to run it and is the slight hangup gone?
Yes it is. Completely.
Could you possibly take a picture of this haircut you gave your carb? (Please)
I think I know what you did but, not sure.
Maybe those reading are interested too
Thanks for your input !
Ok, here you go. You can see the space where the lever was. I had to remove the carburetor, remove the primary throttle plates, slide the primary throttle shaft out and get in there with the cutting wheel on my dremel. It's really tight. I ended up having to finish the cut with a hammer and small chisel. Yeah, I kinda didn't like it either. But I got the thing off without tearing anything slam up. lol
Crap! '...one of phords better ideas' just got, 'improvised, adapted, and overcome'! lol
thanks! I/we will now know where to look.

I have the AVS650 on my 418 stroker for street driving. It has performed very well. I have not experienced any off idle skips or Boggs. I’m running the 6psi edelbrock mechanical fuel pump and a wide band O2 sensor. Before installing a pressure regulator I had inconsistent A/F ratio readings at idle and random idle speed variations. Looks like the valve on the Foats allow fuel to leak past and cause the erratic A/F and idle issues. Don’t know if engine bay heat and no fuel retuen was causing the fuel over-pressure conditions when the fuel got warm. I saw as much as 9psi on the fuel gauge between the fuel pump and the carb before installing the regulator.

If one is good two should be great.. ..

Update
I finally found a car to slide under the Street Demon carb. It is a 1966 Charger with a 361. The previous owner added a four barrel and stock dual exhaust, and badged it as a 383 four barrel. The four barrel setup on it is a little weird, using a 76 400 thermoquad manifold with an adapter to an AFB carb. They had to butcher the air cleaner base plate to fit the carb. I just picked up a Performer manifold from a member here, which will work great with the Street Demon carb, and still allow me to use the factory A/C brackets.

My 750 CFM street demon should be for sale here pretty soon. I'm switching to EFI if I can ever find time to finish plumbing it.

I love the SD 625, like it's been said, not a whole lot to do with it out of the box.
Smaller primaries give it great throttle response and drivability.

I just picked up this Performer manifold from a member here, davescuda, to use with the SD 625, should work well.

You need to move your pump rod so it won’t do that.
Heck yeah man! That's a fine intake!

AVS guy here. Fantastic carb. Easy, convenient access for multiple tune changes if needed. But, agree. Die cast aluminum is a very poor choice with today’s fuel. It transfers too much heat, which boils and vaporizes the gas. A one inch wooden spacer pretty much eliminates that issue. But, a composite body carb is far superior with today’s gas. Regardless, of carburetor. Rerouting your fuel to the tank is a huge improvement with today’s gas. You have to do everything possible, to keep it cool as possible.
