Hi guys, I'm new to the forum. My car is a 66 mustang with a bone stock I6. After browsing through page after page of info and already being frustrated with the search function I have a couple quick questions, and really lay it on me. I happened to stumble upon an offy intake and three rebuilt carbs (2 holleys one carter) for $100 total on craigslist and snatched them up in a hurry. Now I'm thinking about putting them on but I am concerned about cost and difficulty. How do you get the extra holes in the intake? Machine shop or can I do it myself? Starving college kid here guys... Thanks!
 
heres some pics of me cutting the holes in mine.

There is a current thread about installing and tuning a 3 in 1. Check it out.

Spend $20 and get the Falcon Performance Handbook at the link down below. It will answer most of your questions before you know enough to ask them. Best sawbuck you'll ever spend in your life. Although it says 'Falcon', it is about the Ford I6, which the author - our resident guru - has in his own Falcon.
 
That Manifold is for the later flat log style head. It will not fit on the early round log head. That may make it easier for you since you will need to find a later head to modify. You can run the car while you modify the newer head. Definately get the Falcon performance handbook. Someone else has done all the work, all you have to do is decide how much work you want to do.

So how would one go about finding a suitable head and how much do they go for? I may have found an aluminum one near here for $200 I think. Is that a fair deal?
 
The only aluminum heads for the 200 i6 just came out on the market, and I don't think you'll find one for $200, unless someone's feeling REAL generous. I'm guessing you found one for some other engine. But normal 200 heads aren't that hard to find anyhow. I'm sure someone here knows a place (or has one themselves).
 
At our local pick a part junk yards you can get a head for less than $100.00. Then plan on getting it rebuilt at a machine shop. They can also set it up for the manifold. We used a hand grinder and flat file on the head to make the flat spots for the manifold. Jessica's came off a Fairmont. I am not sure about an aluminum head, did not know that they made any.
Hope this helps.

The guys I was talking to said he had a rebuilt aluminum head? Any idea what hes talking about? Also comes with hard stainless valve seats? Huh? I really need to pick up a copy of that book.
 
And he said it was the small ford i6? Maybe it's an Australian or Argie head. Aside from the CI product, those are the only other sources for aluminum heads I've ever heard of. $200 would be a hell of a deal for one of those too.
 
Yeha he said it was for his 65 mustang. :?: Im trying to get a pic out of him because even if I have to scrap the offy idea that might be a pretty cool setup for the money. As soon as I get it figured out I'll post a pic
 
I finally got the guy to tell me it was an original head with the hardened seats. I don't know where he was getting the aluminum part from. At any rate how difficult is it to find a head for a 70 and up? Is this just a direct bolt on for my 66?
 
It's not that hard to find, depending on where you're at. In general they're not uncommon, but in some places it can take a little longer to track one down. If you're anywhere near the AZ/NV/NM area, they seem to be everywhere out there.

But yes, they're a direct bolt in, although since the combustion chamber is larger, you might want to either mill the head or the block, or you'll lose some compression - or you can take advantage of the lower compression and get yourself a turbo setup.

And for your earlier question: Hardened seats are an adaptation for unleaded gas.
