600 CFM, all I need. Check my math!

My thinking is this. I'm new to carbs. The Edelbrock from my understanding, is easier to adjust / tune than the Holley. I have no desire to go to a Holley just based on that alone. The 1407 does not need to be removed from the intake. At my skill level (low for carbs), I need to stick with what is simplest. To learn. Aside from what I believe to be flooding the car somewhat when cranking cold, the 1407 seems to run smooth around town. It also gets crap for fuel mileage, and is low on power. I don't fully blame those last 2 aspects on the 1407. The exhaust is in bad shape. If the exhaust were done (should be complete in a month's time I hope), it would likely help lean it out. But the wideband will spell it all out. And I should be able to tune the pi$$ out of the 1407 to make it run as good as it can.

Don't get me wrong, I'm not expecting excellent mpg in the Scamp. But I use mpg as an indication of the state of tune of the engine. I expect that a 360 cubic inch old school V8 in a 3,100 pound car to yield 20 mpg cruising the interstate. However, with the 3 speed, and turning 3,000 rpm, I don't think it will achieve that. But I think 16 - 18 should be feasible. When I get on the interstate, I cruise (this thing) slow and steady. 55 - 60 mph, and I don't care who or what tries to read the serial number on the bumper. That's why other lanes exist. I'm in the slow lane, they can get left.


They are easy. All of them are to work on once you look at them.

If you really want to get the hang of it, start reading all you can about emulsion and how the carb actually functions. Understand they only know pressure differential. Once you get that concept downy out can understand why you need emulsion. Why air bleeds are needed and how the trim the fuel curve. Carbs are simple in operation, but complex in function.

Work with what you have. There isn't a thing wrong with it. Just tune it. Once you get comfortable, you can start watching the plugs. I've been able to move the fuel ring up and down the plug nose with simple jet changes and also changing emulsion.
