Does anyone prefer quadrajets over sqare-bore aftermarket carbs? Are there any advantages other than tilt angle?

 

I like the Q-Jets. Small primaries give reasonable MPG and decent torque. Huge secondaries when you stab the throttle. 850 cfm and up....

What's not to like? Oh, they're a little bit harder to understand & work on than a Holley.

 

That's what I've heard about them regarding efficiency.

Im looking at buying a 74 K20 with a 454 from my uncle who bought it new, and I'm wanting to make it as efficient and reliable as possible.... and I've never messed with carb'd anything.

 

Biggest thing against MPG's on that 74 BBC truck, is not having overdrive. 8 MPG gets expensive if you drive a lot.

 

They work very well when they are set up right.. That is what they put on about 99% of the boats that ever left the factory.. Even when they need a refresh they work decent. One on my dads 83 bbc dually i do not think was ever rebuilt, runs fine.

 

Im considering a 4L80 or 6M swap and a stand-alone, but id have to figure something out with the right side T-case.
