I was wondering if a edelbrock 1405 600 cfm 4 barrel carburetor would fit on my nova's inline 250 six cylinder?

I've seen it done I think but wasn't sure what it takes? Would I need an adapter plate or special jets for the carb?

Why would you want to? Less MPG, hardly any more power, huge flat spot when you nail the throttle......sounds great!

Cause I got one for next to nothing.. :yes: :turn: I seen a few in this thread and was just wondering.

How would it hurt power? Wouldn't it help because more air and fuel?

Too much of both can be a bad thing. If you dump in a bunch fuel in all at once it is going to bog and run like crap. A 600 CFM carb while big for a six can work if you tune it right. I would start scouring web sites or hemmings for a 4 bbl manifold for a straight six. They make them, just have to search.

If you do it right it should wake up the six without too much of a fuel penalty. Definitely an old school approach.

You can get a manifold from offenhouser or clifford performance or I think stovebolt engine co. But if you got the carb cheap I would sell it and buy either a 390 or 500 cfm it will run a lot beter then drowning it with a 600. Good luck either way

with a stock engine, most don't recommend going bigger than the holley 390 cfm.

I had a 390 Holley/Offy intake on my 230" 6; it wasn't the one most people recommend, and it was way fat just about everywhere. I played with restrictions in the idle cicuit and jetting up and down and got it much better, but it still was unimpressive. You all know how I feel about Edelbrock's so we won't get into that again, but a 600 on an inline is too much in my opinion. For some reason V-6's seem to like larger carbs, but not Chevy inlines without a lot of other modifications. Something like a 32/36 Weber would probably be a better choice.
