lol! No lead floor mats or roll bar. And it's a small block! No Jimmy Hoffa in the trunk either. I actually thought maybe the first scale was wrong but I weighed it again at Norwalk and it was within 10 pounds of the first scale... :/
Wow, my buddys car 68 Dart 440 full cage dana hinged fiberglass hood and bumper weighed 3020 on the scales at Maple Grove.Now these where race cars but only things removed where seats,heater box,wiper motor. Glass and all the hardware still there. Sorry if this got off topic couldn't resist.

Our '76 Dart weighs 3,400 pounds. Our '72 Challenger weighs 3,340 pounds. lol...the later A-bodies are pretty heavy.
My '74 Duster is 3600 lbs with me on board, they are a tad on the porky side and that is with aluminum rims.
Whew! Thanks for redeeming me!
(Sorry about the subject change guys...back to your regularly scheduled Eddy/Carter vs. Holley debate, I'm finding it very interesting.)

Basically, it's a matter of personal choice and comfort. For example Dustergirls' 340 is a "GIANTKILLER" with the Holley, which is great for her combo. Mr. Yuck prefers the "six gun" for his 440, which is a very LETHAL combo! However, the Street HEMIS and Max-Wedges ran great with Carter AFB"s and were extremely tunable. The fact is, yes Holleys' are a bit more "user-friendly" when it comes to tuning than Carters since there are more of them in circulation and the racing industry has had MORE development time with them (Holleys). Carter AFB's can and will run as good as a Holley, IF, they are tuned CORRECTLY for the individual motor combination you have. They are more sensitive to compression, cam and ignition timing, since their secondaries work off of engine vacuum/airflow! AVS's and TQ's are more forgiving, with different engine combinations, mainly due to the spring loaded "air door" secondaries. For most street and street/strip motors Carters can handle most applications (again, TUNED CORRECTLY), but Holley continues to be the standard in street/strip and "all out" racing!

AFBs are for street rods and cruisers, holleys are if you want performance. You will ALWAYS leave something on the table with an AFB.
That may be a valid statement to some, but AFB's can deliver performance too, again IF TUNED RIGHT to the engine combination! Leaving something on the table, you say?
It's called a "trump card" when AFB's are used in dual 4bbL
setups. Always keep an "extra" 10% more, in the back pocket, for when the race is tight (neck to neck)! FWIW, I like Holleys ..but.. I LOVE Carters.

"480 calculated flywheel hp isn't too shabby considering he is grossly undersized on carburetor CFM, I bet it has wicked throttle response." You hit the nail on the head. He'd make much more power with a better carb. A 750DP or even better HP would give him much better performace. Even a thunder 800 would.. I'm glad somebody brought up Thermoquads. I love them, however finding a good one seems hard these days. FWIW a big 4bbl would probably run better on my car, but I've always wanted a 6-pack, I can't afford a hemi

This is a really sophomoric argument.  Arguing which 1950s technology is superior. The Holley 4150 platform first saw wide service on Phord's Thunderbird. And AFB stands for Aluminum Four Barrel because they dated to a time when carbs had cast iron bases. The CarterBrocks are simpler carbs that have far fewer sizes with very few choices. But, when right, they are extremely dependable. The Holley style platform has far more sizes available. And a ton of different combos in each of those sizes. As far as tuning, I don't think that there are a heck of a lot more guys that understand carbs today than there were 40 years ago. So the way it runs their car OOTB determines whether it rocks or is crap. More luck of the draw than precise planning or tuning or even brand. Having said that, I am getting ready to buy the carb designed by a former Carter engineer working for a subsidiary of Holley; the new Street Demon. That way we all win!

For tuning, Edelbrock has 32 different metering rods, at least 16 different jet sizes, 5 different step-up springs, and at least 3 different accelerator discharge orface sizes. The old Cater strip kit adds another 6 metering rods.

I'm agnostic in this  . They all have the same type of circuits and both have +/-. Holleys have power valves that leak or blowout and the carb has to be pulled, drained and flipped to change, the Carter metering rod setup is bulletproof and easy to change. Changing the jets on a Carter can easily be done with the carb on and no draining of the fuel bowls is required. The secondaries are easy on a Holley, esp if you have the quick change upgrade for the vacuum dia. The AFB carbs have issues with the secondary being a PITA to adjust, the AVS Thunder carbs are easy. Comparing a DP Holley to an AFB/AVS is apples =/= oranges, they were designed for different purposes. Saying a DP Holley is better on the track (drag race) than a vacuum secondary carb of any stripe is really a no-brainer. If there is a significant HP difference then carb is defective, poorly calibrated, or otherwise mismatched.

You are confusing tuning parts with carb choices. There are very few CarterBrock choices for a given size of carb when compared to the Holley platform.
That does not necessarily mean that the CarterBrocks are inferior, just that you are more likely to need to tune one rather than find a version closer to your needs OOTB.
But then, most guys don't know how to properly size a carb for their needs, let alone choose the best metering for their application or be able to tune it. So six of one, half dozen of the other.

Granted these Carter/Eddy/Weber carbs are slugs. Dave Dudek, pure stock Super Bee Factory stock 10.92@127Doug Duell "Dragon Wagon" N/SS 9.39@145DVW 64 Belvedere N/SS 9.25@147.7And lets see what have I done to mine? Metering piston spring change, secondary jets up 2 sizes, removed the choke blades. Gee that was hard. For what it's worth Len Adamacks 63 Plymouth N/SS was faster with Eddy's than Holley's. Ya it's a slug also. 8.99 @151. Duell's car now has Holley's still runs the same class, no miracle speed improvement. And yes I also have cars with Holley's. They'll all work . Doug

You hit the nail on the head. He'd make much more power with a better carb. A 750DP or even better HP would give him much better performace.
Again this is just "wishcasting" assuming he would have better performance with a Holley over a Carter of the same size.
He would have greater performance with a ANY carburetor with more CFM than 750, he is undersized for the application/displacement.
ok keep telling yourself that. A holley 750 DP/HP or even a vacuum would give him more HP. I have 3/4's of a holley 750dp in the garage. If somebody wants to buy the rebuilt kit and 2 fuel bowls, I'll rebuilt it and give it to him. If it doesn't run 2.5 tenths faster in the 1/4 mile I'll buy all parties involed a 30 pack of Bud.

Now, a 4150 or 4500 series Holley
