Now that is clever! Good Job!
Thanks! Had to do something so I wasn't forced to run a Holley. :wink:

The 72 to about 74 or 75 TQUAD are best. The 75, 76 truck quads are good also because lack of EPA junk, jets can be found for them or you can take stock ones and drill out. That said there are a few racers that swear the 71 and early 1000 quads are slightly better. I have 4 of the 71's and the ultra ultra rare jet and rod kit for them, but I haven't run one yet so can't say first hand. Big key is to make sure the center section is not warped and is square, and when seting up use the factory spec to start and do them in the order specified in the FSM. If anyone needs the jet drilled LMK
I've found this to work the best for me also. But my cars tend to be more steet than anything else. International Harvester also had OEM TQ's. If I remember correctly they had electric chokes. In general Big block TQ's are richer than small block TQ's and Original HP TQ's are a better place to start when setting up a HP engine. But all of them can be made to run great. I'll also second the "two part epoxy" for the well plugs. Not saying something else won't work, but that is what I use, and have had no problems.
I ran a 71 TQ and stock intake on my 273. On the street, every day, for years, Stock, it made a believer out of me. It was still breaking into 13's in the quarter with a 100,000 mile 340 in a Duster before that. I never understood why they always said to go with a 72 or newer...
Well yeah. The big block carbs have 1 1/2" primaries and the small block 1 3/8". 850 and 800 respectively.
For what it's worth, pretty sure the OE TQ for my '74 360 Duster has the large primaries.

You could do what I did and build a bracket to mount the aftermarket TQ choke setup if you don't have the choke well in your manifold.
Anyone know where to find a new choke cover though? Apparently they are made of unobtainium.
Something else to be aware of though is the transfer wells in the bottom of the fuel bowl. They can leak and cause problems. Rusty, do you have a way of repairing them?
Would the single planes have a weaker vacuum signal?
And would this help make up for it?
The car would NOT be a daily driver.....more of a car show thing and a tear-em-up toy. No strip time, likely, either.

I wasn't including the IH stuff because they have some bastardized linkage and whatnot that makes them more of a parts carburetor for a Mopar.

Now here's the real trick, do it for the easy to get unit from Edelbrock. Ive made it work before I the same/similar manor.
Yes, most big blocks had the 1 1/2 inch primaries. "74" 360's did not.
X2 mostly for the integral electric choke. Never had one myself. Just thought they had the electric choke and housing.
Seems like someone on this thread said something about running an adapter. If so, here's a warning. The adapter I am running would have left me with a huge vacuum leak if I had just bolted it down. I had to run some extra plates and gaskets (from Edelbrock, but don't remember what they were for now). If you run an adapter, check it with the TQ before just bolting it down. And if possible, smooth the transition between the adapter and intake, mine had a huge shelf that would have been an issue. Just some info.
That was me, and I am hoping to NOT use an adapter...I know the pitfalls.
...The #6454 that is right for my car, and is on the car, has 1 1/2" primaries. It's not the one that came on the car as all I got was a shortblock when I pulled the car out of the wrecking yard, but the number's are right. Per the info that Gary Lewallen (aka Vaanth) put on the internet, some of the '73 340 cars had TQ's with 1 1/2" primaries (specifically #6339 and 6340 for the CA cars) and most '74 360 cars had 1 1/2" primaries (#6452, 6453, 6454, 6455, 6488, 9002 and 9004). There appears to some '74 non HP motors that came with small primaries (#9013 and 9022), but it appears that all HP 360's had the large primary TQ's. I could be missing something, but I'm 99% certain my '74 360 did come with 1 1/2" primaries.
Most of my carbs are not at the house, so I can not confirm or deny. I do have a couple 6453s as they are desirable. I will bow to your "99% certain".
Hope I didn't come across as argumentative. Wasn't trying to throw anything in your face.
Rusty, are there certain mods you do to a TQ for street/strip application that you would recommend?
