Now I know this seems silly, but.... The 1406 has a "Black" version. It would go well with the color combo Im trying to go with...
Is the 600 CFM going to be harmful, cause any problems or be just a plain old bad choice for the L6?
Thanks again!!

OK, So you've got a 250. right? Why do you want a carb that's made for a 350?
Drag racing? Going uphill both ways?
They used to say Less is More about carburetors.
I once tried a 780 CFM 4150 Holley doublepumper on the V8 350 in my GMC K/1500 Jimmy. Ran great on the freeway, but would stall out after getting off the offramp. Finally it ''sucked valves'' -- the pistons on #6 and #7 smashed their sparkplugs. 350s normally run 600, 625, 650 max, carbs. I wound up replacing that engine.
Now you may not get into much trouble with a vacuum secondary type carb like the Quadrajet or Carter AFB -- since it only draws as much Air Fuel mixture as it can use. But a 600 CFM carb on a 250 is too much IMO.
An Edelbrock tech rep once told me ''You can put the smallest jets you can find on a 600 CFM carb, but it's still gonna flow 600 CFM.''
''Because it's black'' is an unsound reason, mechanically. Who's gonna notice, anyway?
