Carb Swap?

@Paladin would be Proud of you! Lol

Except it's a spread bore holley, not the squarebore type, I think he's partial to the latter.

I always enjoy the Holley/Quadrajet debate. The fact is the Quad was built as a street carb, good manners and good fuel economy. When the big 3 wanted a higher performance carb, they all looked to Holley. More air/fuel for the high performance muscle cars of the 1960's. Fuel economy, emissions, for the Holley's, not so much.

Holley, very simple and easy to tune. Speed shops across the nation had anything you needed. In the 1970's as the emissions regs. came in, things started to change. Highly re-engineered Quadrajets, became in some cases, a better choice. (for you @Ricko1966 )

I'll still stand with @Paladin Holley's are easy to use and understand. Parts are still easy to get online. He!!, you can re-jet without even taking the carb off the engine.

I have zero problem at all with this. Holley is the simplest carb to tune. I like quads because they are so refined,but if you can't set it up right,all the refinement in the world is of no value.As a replacement carb,holley would be my second choice. Besides a properly set up quad.

Maybe im wrong about its origins but here it is. This thing makes me smile

Not to threadjack, but it looks like you have much bigger problems than your carb. From the pictures, the cold light, the lack of color saturation, you are living in the world of "Battlestar Galactica" or "The Road" -- a dystopian sci-fi near-future hellscape! I'd stop futzing with your carb and check your compound's perimiter right now....

Q jet design is a good compromise between economy and power. They have idiosyncrasies that anyone experienced can deal with. People dislike them because they don't understand the design.

For modified mild performance engines the Carter Edlebrock carb is a good choice.

I will take a Q jet every time if originally installed on a GM vehicle. Reason I say it that way is some high-performance GM vehicles came with Holleys.

You’re speaking my language. I’m old enough to have had experience with them but I was never around them. I’m sure it’s not rocket science, but when I fire up mine with the Edelbrock and it runs fine, I don’t see a reason to go back. Well, technically I wouldn’t be going “back” because my truck was a 250 I-6. It would take a guy sitting with me and explaining how they work in person and those guys are hard to come by.

The two things I will say about an Eddy is that you can walk into a parts store and get a rebuild kit for one most places and they’re easy to work on. As far as all out performance, the evidence suggests there’s better out there.
