Hello all, long-time board reader, just joined. I have a unique situation, and YES, I have read the archives. Currently, I'm working on a 69 Chrysler 300 Convertible w/ K-code 440 that is 95% restored. I don't believe I have the trailer tow package/3.23 gear. My AVS carb (which worked flawlessly FOREVER) finally dried up after sitting for several years while I was away. I want to rebuild the carb. It always worked so well, I'm afraid to change. What is a good replacement intake? I want something aluminum. It HAS to fit under the hood (no hi-rise). I would also like to do as little "fiddling" as possible with fuel lines and linkage. Right now, I've got the stock cast 440 intake of '69. Keep in mind, unlike most of your A/B-body guys, I'm looking for kick-you-in-the back, STREET TORQUE. This is a cruise-in car, NO track duty. I know I'll probably get as many opinions as responses! Most of my local Mopar friends are track/HP freaks, and they recommend "go-fast" 1/4 mile parts, which I know won't work on my car. They can't understand why I want to mess with these worthless C-bodies. On hand, I have a Streetmaster 440. I also have a '75 truck TQ carburetor, also needing rebuilt, but I really LIKE my AVS. I also realize the TQ/Streetmaster combo is not exactly period correct. Eventually, when the time comes, I plan to upgrade the car to TNT specs, with a Hughes cam and an Offy low-rise dual-quad. I already have a pair of matched AVS carbs setup for such an animal, but that will be something I won't do for many years down the road. Depending on how much I like the single-carb setup, though, I may just unload the dual AVS carbs and keep what I have. Uploaded with ImageShack.us

I would convert the OE AVS to the eddy 2 step metering rods/short pri jets. All OE AVS's are emission carbs & are lean & AVS 3 step rods/long pri jet strip kits are extremely rare to come across. You wont regret it.

Not as sure of fit as I used to be after reading all the posts on here, but I would go with a simple Edelbrock Performer intake and the thermoquad. They really do keep the fuel cooler - which is even more important than it used to be with today's gas - and should be a little bit better on fuel.
Plus you should be able to get that air door tuned perfectly to get that land yacht off the line no matter how much pedal you use

I thought that too, but haven't read too much about the regular Performer (from users, anyway) everyone bolts right to the "buy the Performer RPM" mantra....and fiddle with hood clearance and linkage for 2 days. No thanks. If you check the Edelbrock site, the "power graph" they give you with the regular Performer states it is WITH the Performer PLUS cam kit...sorry, but if I'm going to go INTO the engine, I'm going to go a whole lot further than a Performer Plus cam ONLY. Yeah, I really WANT to like Thermoquads, but I just never had one that worked as well as this AVS. Plus, mine has got the goofy bowl venturi vacuum port, and the "extra" vacuum port on the front. Call me anal, but I absolutely _HATE_ when I have extra ports I have to plug with caps.

Yeah, the later ones when they went crazy with the emissions stuff are a pain.
What RPM range you want to use? Even a basic dual plane like the performer should be good for a 6000 rpm shift. Plus I think it would help with vacuum signal (idle and brakes). two VERY important things on a huge car... LOL
We had a different 340 TQ, not sure what it was about it, one of most rock solid and reliable carbs I've ever seen. but they just aren't all like that, and it's probably luck more than anything

It's a great intake for a torque/street application, that's why I thought I would suggest it for a C body. We've had the smallblock version on a 318 for years and years and it ran great.
If you look around, there are lots of dyno comparisons for intakes, and they always include these. If I remember correctly, it always holds up well, except into the 6000 range. but to me that's not a realistic range for a heavy street car anyway. might as well keep midrange and manners

I wouldn't fiddle much with carb and intake...under 4500rpm without some kind of cam change. I'd think about a conveter with a 2800 stall. A good quality one has excellent street manors. It will give you nice torque right now.

rebuild your stock carb, recurve the distributor and call it a day. the ch4b or performer intakes would work well in your application however other than shedding 10 lbs you will see no difference. a waste of money imo. if you were putting in a cam I'd say ok. but with the stock cam in there your car will see no gain.
