needsaresto - I would have used a good working TQ, but wasn't interested in a builder online, too risky and not enough money left in the budget to horse around if it had a busted body, needed a kit and who knows what......
I bought a really clean looking (looks like new) 1405 Eddy 600 cfm carb that was suppose to run great when pulled from the car. I gave 85.00 shipped to my door (it's on it's way). It fit the budget and it will work great for this combo. I'll post pictures when it arrives. Regardless, this is the carb that will throttle this 318

That's exactly how to fix them.

$85 for an eddie is an unbeatable deal. Can't argue with it,and I would have done the same.

The headers do seem to make a big difference from stock.
That's what I can't help but think. If the 2bbl was still there it'd be the trinity to keep it way up in the clocks.
It's funny cause it doesn't take a whole lot to make these cars able to do 120-150 with the highway gears like they but they sure didn't stock. Interesting what such seemingly small numbers (like 30) of horsepower can do. Apparently 225 and A/C often got 3.23s. I forget the multiple of the 2.9 for the 8-1/4s and 7-1/4s but I think that one was actually very common on base I6 and V8 cars before the 2.45s came out.

I was thinking a tq might help the op make his h.p goal. Personally I'd be interested to see a real world test/ comparison between the Eddie and a tq. Idid swap out the tq on my 318 cop car for a 650 Eddie. Lot more power with the tq, especially when I threw an 850 cfm tq on it.Yes I know an engine is limited by it's cid in what it can use. Might have been the 360 heads like more air, but it also was a log manifold exh motofr and a 2.5 single exhaust pope
A friend of mine ran a Holley 750 on his 318....Ran freaking awesome!
Didn't seem over carbed to me.....damn car was f ast!
Donate. Temporary TQ loan.
The 750 Holley was busted and tuned correctly then.
A lesson many have not learned yet. It's just instantly to big.

I hosed them with high pressure water, blew them with compressed air, and soaked them with WD40. ....so that's why they look wet.....
I think they'll breath a LOT better now!
Not the prettiest, but it's my first time. ....
I believe it'll be very effective

Might want to smooth those babies out a little bit...?
I'm definitely not done yet!
Scotch brite buffs on a dremel work very well to smooth / blend
Yep, shine up the chambers, polish the exhaust and you can leave the intakes a little rough. It is supposed to help break up the fuel molecules. (or so I have heard)
- As I've stated early in this thread the TQ would be the best carb for the cast intake spread bore. I don't have one ready to go so the eddy will work.
60.00 - intake
30.00 - porting heads and cleaning
58.00 - All gaskets (including more than this project will require)
48.00 - Eddy valve springs
110.00 - cam
5.00 - valve grinding compound
85.00 - carb
Total spent - 396.00
Left in the budget: 103.00
I have bought and received some other things for the 103.00 that's left. I will post later on them....
But for now, I'll talk on the carb.... and post pictures

Carb came in today and looks Great!!!!! I would like to say that I went on ebay and asked if they would be interested in a "buy it now" option (through a message) to folks that had great carbs for sale for a low starting bid. This guy had this carb that was just listed and his starting bid was 75.00. I asked if he would do a "buy it now" for 75 and 10 for shipping, and he agreed. If you are on a budget, sometimes you need to be the aggressor and don't be discouraged at the first "no".
And here she is.....
this "spread bore" design will help with the cast intake spread bore design.......
These are Square bore based but Spread bore design by the ports.......
I can still smell gas, so this was run not very long ago, which is nice! I'm betting this is a bolt and go. However, I would like to say that if anyone is breaking in a new cam, be sure to use a carb you KNOW is in great working order. You do not want to fight a carb when you are trying to break in a new cam.
I would also like to add that you can go 100 cfm's more on a dual plane than a single plane intake. In other words, a single plane intake with a 500 cfm carb is like a dual plane intake with a 600 cfm carb. Obviously I have the cast dual plane intake, the 600 cfm's will be just fine.

My friend, I have Holley's, but I'm trying to do this build as if I only had a 318 2bbl to start with, and not quite 500 bucks. Thus the reason for every thing and purpose that I have done this far. I want this to be a "true" build that can be followed. Digging into what I might already have would not make this build as real. Please continue to follow along...

How many is too many?
Once you get your base line on the budget you can do a new thread with comparisons on individual changes such as the Holley....
That idea could be fun as well. At this point, though, this car is going to be a driver so I'm not thinking headers, gears, or converter. I will forever be tuning on the car, though, because that is how I am...........
Yes. I have made this argument before only to be told I was wrong, but it is correct. The smaller Eddelbrocks like yours are square "flange" carburetors, but spread "bore". Somewhere along the line, people started getting the two confused, but that is the correct terminology.
A 750 would lose a lot of responsiveness out to the smaller Edelbrock, because of the much bigger primary barrels, not to mention mileage will suffer. Velocity in the Edelbrock is much greater and will equate to much more crisp acceleration. Besides all that, the secondaries on the 750 on a 318 probably wouldn't begin to open until 4500 plus RPM. Kinda useless in his application. The Edelbrock is perfect.
I will again applaud this build. we have so many first time guys show up here with their newly found prized mopar. usually it is get it ruuning/driving decent first... and with a BUDGET,... later comes maybe more performance into the equation.
not everyone, young or old has it in their budget to take the engine to the machine shop. $2-3000 bill!????? some of us older guys enjoy the deal of getting a cheap S B dropped into a lighter car for decent fun! continue on!!!!
buying a good Eddy carb off feebay for $75 clams makes me all warm and fuzzy too! ha

All was someone shitting on a posters thread trying to do a good thing. And then trashing his idea or use of a cheap part to stay within budget. Always a argued to say *** is better than your choice.
Good Lord, STFU!
Spreadbore carbs are;
TQ
Quadrajet
Holley has a couple as well.
The slight offset between the primary and secondary of the above mentioned Edelbrock carb as well as others do not make them a spreadbore carb. Split hairs if you want to.
I make this mention as not to argue but point out traditional ways of looking at the carbs.
