The older Holley 750 on my fresh built 383 stroker is junk. What would be the best non Holley carb to replace it with? The engine is supposed to be able to put out 500 hp. I don’t want to go to big, but I want one to handle power. I’ve been told everything Edelbrock 650 to 800. The car won’t be a racer just a street bruiser.
Which carb?

How old is an older Holley 750? I would probably rebuild it and if you want to upgrade it you can get things like adjustable billet aluminum metering blocks etc.
The Demon line of carbs is supposed to be pretty good from what I have seen about them.
And theres lots of models to choose from;

And here is a chart to help find the model you need;

My mechanic did a rebuild, it ran ok for a while now its self flooding. It’s 15-20 years old, mostly in storage .
Sometimes it's easier just to replace an old carb,especially if they are giving you headaches !!
Been there and done that LOL

Doug,
Maybe consider a well built Q-jet, newer Holley, or a Demon, as Guy suggested. My friend has a Demon on his 403 Olds and he loves it. His old Holley 750 gave him alot of trouble.

I am far from an expert on carburetors but there are a lot of people who say that a well built Quadrajet is the best carb you can get.
While I agree that a well built Q jet,like one from Sean Murphy Induction or one of the other well known Q Jet builders,would be a good choice,it kinda sounds like Doug might have a square bore intake.
