He loaded it up and it backfired, Don't know how he did it but the carb never worked after that. I even rebuilt it and had a pro take a stab at it.
Relax, all right? My old man is a television repairman, he's got this ultimate set of tools. I can fix it.

So how many power valves do you have to replace on a six pack after a backfire?
Only one just like any other old holley out there...And if it's backfiring your not getting fuel mileage or performance tuned like that !!! ...I'll take the 6 pack thank you...I can show you the good gas mileage I get right up to the point where the other two carbs come in... ..

Tom, you and your friends have a ton of real world on track experience, no doubt, you get my full respect, and I'm not saying you are wrong or right, as I mentioned I would tend to agree that in the end a Six Pack would probably edge the TQ. However, so far have not seen any valid real world proof (controlled dyno or track testing as I described) supporting it either way, including the example you used.
Chryslers ratings were often manipulated in the name of marketing or the insurance industry, and as far as the NHRA goes, I don't agree with MANY of their factors.

Hey Scott, Here's the thing... Chrysler thinks its 15hp better, NHRA thinks its 14hp better and some guy I know thinks his car doesn't go as fast with a thermoquad. How is that for scientific?
Question- 15hp better than what, the stock cast iron 340/440 intakes?
Why yes, then you would be correct.

If need be I'll be happy to prove it. I'll have a new car coming out soon that I think would be the perfect test bed. It's a 72 400 Charger,TQ equipt of course. I'd have no problem swapping a pack on at the track,I own the parts. The car doesn't have fresh air so that wouldn't be a factor. I have the ability to set the A/F ratio in either setup to the other. I'm well versed in both setups. Its 8 bolts to me Sounds like fun I'd be willing to bet on the pack by about 3 mph. If someone out there has a B engine spreadbore dual plane aftermarket intake I could borrow I bet we could close in on the pack. We could always toss a TQ on the Bee I'm sure that would slow it right down. I would have to see if I have any 440 TQ manifolds.

I have ran 2 440s with the Edelbrock dual quad package. 2 500 cfm carbs with a 1 to 1 linkage. Great great and GREAT performance and looks! I know it not a mopar OEM offering but it is an era correct hi po set up. Its about half the price of a sixpack and easier/less expensive to tune. Id LOVE to see a shootout between the Six Pack and the Edelbrock CH28 with 2 4bbls.
Keep old mopars alive.

I have no experience with a tq, but I cant complain about my 6pack, it just runs good. I have used a performer rpm airgap with a carter avs- I wasn't too impressed, then I went to the sixpack on a Weiand/mopar crossram- it ran a hell of a lot better, but didn't really pull below 3k. Then I swapped to a factory sixpack manifold, low end came back strong, but it did lose a bit up top.
