What will I need and what are some good recommendations on 4bbl carbs? I would normally stick with Edelbrock but I would like to hear what good, or bad for that matter, experiences others have had with different companies. I'm not sure if I should go with a aftermarket company or try to find a 4bbl intake/carb from Ford and stick with that.

My plans with the car (for now ) are only to help her breathe a little better. I'm just looking at doing a 4bbl carb, a good set of headers (also need to know where I can get some of thoes,) and have a duel exhaust system made for her.

Thanks for any help.

The intake ports are different size for the 2bbl and 4bbl (at least on my '65 390 heads) so you should use an aftermarket intake designed to mount a 4bbl on 2bbl heads. For headers, I used Doug Thorley Tri-Y's from Summit Racing on my 302 and like the way they fit. They should have some for FE's also.

Hmmm, anyone else have any input to this? And who would I be able to get an intake like that from if that is the case?

There are no 2V or 4V port designations for FE engines.There are however a few different portsizes.Low,med,high etc,etc.64 and down (maybe some 65)are the lowriser portsize (same as CJ)Most of the stuff you will come across will be the (shorter) med riser port size but i have seen many aftermarket intakes with the lowriser ports.Like i said there are a few port sizes but 65 and up 390 are pretty much all the same.If in doubt just measure the port.

Hey thanks. I called my local speed shop yesterday and asked them about it (plus I needed to order a new master brake cylinder)and the guy said there is no difference on the '68.

He gave me a quote of $350 for an Edelbrock intake and $289 for a Holley carburetor. I want to call some other places or look online too see if I can get them cheaper but I don't think thats too bad a deal, so I might go through them.

Sorry for the misinformation. When I had my 390 2V rebuilt, the heads had to be replaced and when I got it back the intake ports were taller. The first 4V intake I found was the right size and being more familiar with 351 Clevelands, figured it was the same thing on the 390's.

FEs can be very confusing sometimes.There are 5 or more port designs for the 427 alone.

I have a 390 4v FoMoCo cast iron intake you can have for $25 if you want to pay the shipping. It weighs about 75 lbs.
I would reccomend a Autolite 4100 series carb. Ton's of them around.
Simple and works great!

Let me think about it and see. I might want to stick with the Edelbrock for the performance of it but $25 is a lot better than $350 from my speed shop or even the $247 Summit racing.com(<--Click there to see the part they have) wants for it. I see you are in Lyons, IL, how far is that from Hammond IN?

If I do decide to get it from you I can just pick it up from you. I'm going out too Hammond at the end of next month to visit my sister and that would be a lot cheaper than shipping it.

But I still don't know. The Edelbrock one is all aluminum which will save some weight and is supposed to have better performance but no matter how you slice it $25 > $247

What kind of condition is the intake in? Do you have any pics of it?

I am heading out there next weekend and I am thinking I might want this till I have the $$ for the Edelbrock.

Let me know how I can get ahold of you when I get out there so I can pay you and pick it up. But If you don't mind I'd like to see pics of it first so I know what kind of condition it is in.

Thanks

It's 39 years old so it's in pretty good shape considering.
It's cast iron and weighs 75 lbs, and it's a little rusty as to be expected.
