600 CFM, all I need. Check my math!

You guys bring up an excellent point. I understand the principle behind vacuum. But I have no vacuum gauge, and no relevant idea of what I should be running (as far as vacuum). I can tell you I'm reading the Edelbrock carb manual, and it is very informative / educational, and well written. Easy to understand. I believe it also makes mention of expected vacuum, so I'll go back on that. I've dabbled a little bit here and there doing what the manual suggests. For instance the car was idling low and almost stalling when in gear (like stopped at a light). Even when fully warmed. So I read up on where the LA 360 should idle. It was idling (as I recall) 550 - 600 rpm. And near stalling. I read that it should be 750 - 850 rpm (as I recall). So I targeted 800 rpm.

I read in the Edelbrock manual how to set (I think it was) "Optimal Lean Idle." And it covered how to set the rpm, then make adjustments for optimum lean. I'd have to go back and look but I think it mentioned reading vacuum too, probably as the best way to set Optimal Lean Idle. But it also covered how to do it with no vacuum gauge. And I followed that. Like I said, a well written document to include pointers how to do it with no vacuum gauge. In the end, the Scamp now idles spot on 800 rpm (in Neutral), and maybe 775 or so in gear. It does not feel at all like it's going to stall at traffic lights, and comes right up off of idle, at small to medium inputs. If I just instantaneously whomp the pedal to the floor from idle, it will more or less just discontinue running, no rpm increase. I'm not concerned about that ... until AFTER the exhaust is complete.

QUESTION: Can you guys recommend a good beginner's set of vacuum gauges?
