Stock 340 carb????
Got a 1973 stock 340 and it needs a carb, just wondering what carb i should get cause the one on there is a 750 holly and it needs a rebuild. Seems like that carb is way to big for what i have anyways. Was thinking about a holly 650.
Comments welcome Brian |

The stock carb was a T-Q and can be had from Demonsizzler rebuilt and well tuned for your car.
http://www.thermoquads.com/ Otherwise, a Holley 650 is fine. The 670 Avenger is also an idea. If you like the Edelbrock carbs, I'd recomend the AVS unit. The tuneable air door is great. I like OE Carter AVS' myself. |

im thinking about getting another holly, so ill check into the 650 cfm. What about a choke (electric or mechanical)?? what you think

I think a electric choke is stupid NOT to have on a everyday ride. Comes set for the most part. Just wire it up and forget it. Done.

Well in all honesty the car with the 340 is getting sold so im just trying to figure which is best as far as the motor and the pocket book. Did anyone ever check out the air/fuel ratio with the stock motor and an 800 cfm?? It seems like it would drown the hell outta the motor? Unless the carb had very small jets in it. Brian |

Brain;
The secret to the T-Q and it's huge cfm's were small primarys and of course proper jetting. The secondarys were huge. 2.25 each side. Thats alot. This carb is capable of good mileage and smoking W.O.T. performance. You could tune a Holley 1150 Dom. to run on a 318. But in real life, it will have crummy street manors and throttle response. The stock 340 was posted as a 275 HP engine. This would suggest in a drivers car, like everyday, commuting car, grocery getter, etc... 600 cfm would be enuff. |

Where are you located. Just my kind of car. I got a Duster instead of waiting for one to pop up.
On the Cheap? OR new parts? Theres so many ways to go on this. I would get a OE intake and carb for the year car. Stock coil is fine. If not, a basic Accel will do just as well. If you find the square bore stuff pricey, the get T-Q intake and carb. |

I'm close, I have a '76 Duster 360 4 spd and I'd put the same thing on both. A Weiand 8007 intake an a stock 800 Tq. IT's the best small block set up made and it all bolts on. I'd use a stock coil with the stock inginition. Without a complete upgrade your just wasting money.

Hey DW, whatcha get for a stock coil down there?
Also, what do you do for the choke on a T-Q when it's on top of a Action plus since theres no choke well. Cable? |
#12
|
||||
|
||||
Coils run $25. About half the price of an Accell or MSD. I'd run an MSD though if I upgraded the rest of the ignition. Most of the time I don't run chokes, it stays so warm around here about 10 months out of the year, but I have run cables and electric chokes too. What ever you prefer to use is fine with me, I know women have problem with cables though ... LOL!!

Have you been able to run an electric choke on a T-Q on top of a Weiand intake?
I made a adapter, ugly ruff draft, but it worked useing a AFB choke bracketed on the side, bolted to a plate that slid under the carb. |
#14
|
||||
|
||||
Yes, I have a TQ with a stock electric choke on it. I only have one though. I can't seem to find another one. Pretty shure I got it at Advance, but that's been some time ago.

Im located in Wisconsin, alos when you say t-q is the thermal quad for short?
Plus where would a good place to get all this stuff??? Jegs?? Summit?? Brian |
#16
|
||||
|
||||
TQ is short for THERMOQUAD. And yes Summit is about the cheapest place to buy engine parts from. The 8007 intake is about 184 and you can pick up a carb from Advance auto new for about the same price.
|
#17
|

|
||||
Yes T-Q is ThermoQuad. Stock stuff is found here in (Or other places) in the classifieds or swap meets and of course, Junk Yrads.
The aftermarket is very easy to find @ sumitt or jegs. Once in a blue moon or less, E-bag will have a electric choke T-Q on it. Mostly a stock offering on a one year Ford engine. I think it was a 460. |

The reason i asked about the intake is because the setup currently on there is a holly 750, with an edlebrock intake and the carb (with the hard line attached for the fuel) is hitting the coil attached to the intake behind the carb. Is this the wrong setup?? or do i need a spacer so the fuel line doesnt hit the coil?? I bent up the fuel line and all i did was knik the line and it leaks now. So im looking for a setup ( intake, carb, coil..) Where everything is gonna bolt on and not have fitment issues.....

The fuel line should run toward the front of the engine and rubber to the pump. Replace the line.
What intake? |
#20
|
||||
|
||||
It should not hit at all. The 8007 will bolt on just like stock and wont hit on the fuel line or anything. IT's one of the few intakes that was built for a Mopar instead of being a chebby copy. That's why the stock TQ bolts right on. And so does the coil. I noticed the newer intakes do not have the choke well for a stock choke, but I own some older ones that does have a choke well. With a lot of people using electric chokes I guess they dropped that.

this is a manual choke carb, the front of the engine....meaning towards the firewall?? And yes theres rubber line to the pump. As far as the intake goes, how do i know whick one?? ill go out and look if someone tells me what to look for...
Brian |
#22

|

Shoud be a name or number on it to tell what intake it is.

Here's a link for the intake. And it's cheaper than I thought. Only $175.

The front of the engine is towards the water pump. The rear of the engine is towards the fire wall.
The fuel line should go to the front of the engine. Rubber line from there. Yea, on the name, on the intake somewhere like the runners or the base/floor up front and/or the back. |

Hey thanks for all the help..........and the link!!
You to rumble... A couple more things though When rumble said the hard line for the fuel on the carb should run to the front of the motor, does that mean towards the firewall or the front of the car? I know its a dumb Question but maybe the damn hard line is installed wrong. And Does a coil usually sit behing the carb on the intake with a braket around it??? Thanks you guys are a super big help for me!!!! Brian |
#27
|
||||
|
||||
To the front of the car and yes to the other questions.
|
#28
|
|||
|
|||
Unbelieveable.....I know 4 sure the hard line is installed wrong, its going to the back of the car (firewall)....Ill wait til tommorrow to check on the intake, the neibors will wake up with a gun...lol
Thank you guys so so much!!! brian |

hmmmm.... with that hard line installed wrong would that cause the carb to be spitting and sputtering??

Being kinked/bent, yes, but theres more to this story I think.
