I searched but didn't find any real definitive answer. Has anyone powder coated a quadrajet and does gasoline have any I'll effect on it? Just curious not sure if I'm actually going to do it or not.

A quality powder coating should not have any ill-effects from the gasoline or any other chemicals for that matter. Look at Edelbrock, that Endurashine is powder coating and is not quality, in my opinion. It won't flake off though. That is a good thing. Just discoloration from gasoline varnish/ethanol (white deposits and dark marks). It will clean off though with brake cleaner. Takes a lot of scrubbing. Do NOT toss it in the Berryman's Chem Dip. That will take OFF the powder coating!

Cool, thanks Ethan. May practice on a broken main body that I have laying around. I'm going to be bored this winter so I'll need something to do

Not a problem. Let us know how it turns out. A great Winter project!

Have you done this yet? If so, how did it turn out?

I haven't done it yet. I don't have any decent colors right now, just mixed sweepings from different projects. And the color it comes out as is a marbled pink and brown lol. So I need to pick some new up. On top of other things I've been doing tile floors in the house so everything else has been on hold for a few months. Bit as soon as I get it done I'll put up pics.

Please don't forget to post photos when you do it. I am curious as to how it turns out!

I do a lot of powder coating and restore old motorcycles for fun and profit. I use powder for almost everything but not on engines or carbs anymore. Here is my 2 cents on powder coating a quadrajet.
It can be done but the reason I quit doing it is the castings are way to porous. So no matter how much you clean and bake to out gass the part its never enough. When you cure the powder you will have tons of tiny bubbles from the hi temp curing process. The prep would also be a nightmare. powder is very thick and strong so you have to be very careful in clearance areas, every hole and orifice needs to be plugged. If you get powder in a thread hole then cure, it will be very hard to remove. I have snapped taps trying to remove powder from threaded holes.
A good powder with proper prep will stand up to oil and gas without leaving a mark. its just very unforgiving and not the best option on certain pieces. If the carb comes out bad you would need a special stripper like B15 or Rapid strip to remove it. Sand blasting or air craft stripper wont even touch powder.
A better cheaper and just as durable option is Cerakote. You spray it on with a regular spray gun and only requires a low temp over cure that won't cause out gassing and is not thick like powder coating. the chemical resistance is excellent and wont even come off even with paint stripper. https://www.cerakoteguncoatings.com/resources/files/testing/ChemicalResist.pdf
