318 alminum intake?
I know the 600 Ed used carb I have is too much but I have it in my parts stash. Maybe I can trade it for a smaller one. Main reason I like the aluminum intake is easier for this old woreout man to change on that engine sitting in that car!! I will post a wanted ad here and see what appears!!!
Hello All, have been reading through this post of the hunt for an Aluminum 318 4bbl manifold. Thought this would be a good place to jump in here on Post Page #24. Think I know kind of what barbee6043 would like for his simple 318 low compression driver.
Been through a lot of this already on the hunt for a manifold on my buddy's performance build 318 with 318 heads. We settled on the LD4B and are extreamly happy with it. One of the biggest deciding factors was the port size of the specifc 318 manifold and the ease of port matching to the 318 heads.
Mostly everything else we looked at turned out being too large of ports for the 318 heads, like large port to small port. Anyhow everyone knows where I am going with this. We love the LD4B but now they are getting super rare and anyone that has them gets a premium for them.
Here is a simple cost effective way to get a 4bbl on his 318 and get some more fuel into that engine and have the secondaries to play with. Worked for me on this low mile original 69 318 that I did not want to open up and loose the originality on, but I knew i wanted the 4bbl and knew that 318 was just begging for more fuel just from the sound of it. Nice having the secondaries to play with now too. Edelbrock 1406 bolted right on, no rejetting and just runs great, and to my amazement good performance and 20 mpg pushing the car around with the 2.94 gears. That is a dual plane stock 318 2bble intake that does not need to be port matched because the ports match from the factory. Here we go:

We have these LD4Bs but are saving them for our performance build 318s:
This setup above with the air cleaner on the Edlebrock on the red 318 was the first day rough draft setup. The next day I did a little machining on the Mr Gasket 4 to 2 bbl adapter where the mount bolts go to the manifold and used the below grade bolts with the kit to keep them out of the way of the butter flys opening up, then I was able to get rid of that carb spacer, drop it down, and make a nice clean install out of it.
Very happy with this 4bbl adapter setup on the 69 318, runs, drives, performs just fine. Popping on the the LD4B would wake it up even more, but it is a stock original and runs just fine now. Even the tone of the engine deepened up with the added fuel available, but yet still great mileage.
Kind of Unreal.
That is what is fun about this stuff, finding things that work out. Thanks
