intake manifold
 

The rules say you can't touch it, no mods, but final say so is left to the discretion of the tech director.

As most of you are aware of, its easier to win the lottery jackpot than it is finding an unmolested 45 year old manifold, specifically in my case (D1ZX-9425-DA) and, the ones that do have them....well you can cast it out of solid gold and it would be cheaper than what they want to part with it for.

With that being said, It seems like everybody is an expert at modifying and had to get in there an "notch" or cut away the center divider.

What gives here? minor notching? cut it ? drill holes in it? or leave it as is? I know what the rule says, but what does the tech man say?

How much luck would I have getting an "approved" aftermarket intake to fly as long as it is the same configuration

Hey Bill if you want to run a 4300d carb i know were you can get a nice CA intake.

Re: intake manifold
 

The blue thunder is supposed to be a copy, I am going to see what they say about that.

I need the standard holley pattern, I need to use my carb:D

Re: intake manifold
 

For the Bow Tie and MOPAR folks, he's talking about a BOSS 351 Holley 4bbl intake called a "Buddy Bar". It's a performance specialty part according to MustangTech.com and very hard to find.

Just say No to 4300...

Re: intake manifold
 

It should be NO problem to get a manifold accepted for your application. Just like the 502 crate motor gm performance manifold accepted for the 396 375 Chevrolet.

Re: intake manifold
 

Bill,
The Blue Thunder happens is an identical copy of the D1ZX-9425-DA intake. Will not be surprised if the guys at Blue Thunder purchased the original tooling from Ford like they did for many of their other offerings.

Just submit it to NHRA for approval like many have done for other applications.

Re: intake manifold
 

I did, waiting on a response

Re: intake manifold
 

Bill,
Those are showing up all the time on E-bay. If not there, there's Perogi or other Mustang/Cougar resto sites. But yes, they're spendy.

See if you can get them to approve the ford Motorsport m-6049-A3 cylinder head,seeing how ford built it as the replacement head for the Boss 351 per the 1984 ford Motorsport catalog.

Re: intake manifold
 

Good luck with that, I don't think they would like the raised exhaust port.....the cast iron are fine, they are some bad boys with the right valve work

Question....has anybody rung up a 9 sec pass in legal stock eliminator trim with a small block ford yet?:D

Re: intake manifold
 

Just missed bidding on a DA intake about 6 hours ago on eBay it went for 500.00 and it was untouched still had carbon soot build up inside of it.D??

Re: intake manifold
 

I don't get on Ebay much every time I do I get outbid.


This is the Blue Thunder I would like to see approved #IM-351C-4VC

Re: intake manifold
 

For a cylinder head to be approved, it must be currently available.

Re: intake manifold
 

Well...............so much for that plan. Next?


Bill,

After reviewing your request, there is a significant difference between the Ford and Blue Thunder plenum divider. With that said your request to allow the use of the Blue Thunder intake is denied.

Bill,
What part # heads do you use? I think I have a set of 351 4bbl or 302 boss heads stuck back in my core building. I've had these for ever. I think they are pretty much virgin. Is the water passage in the deck the only difference? I've got old timers and can't remember.

Re: intake manifold
 

Mostly yes on the diff, Adger. There were some Boss 302's with 2.25 intakes. One year I think.

Heads, probably either the D0AE-N or the D1AE-GA if claiming as a 71. (there's 3 #'s for a 72 275 horse engine which are neither of these) Which I would be looking for myself if I could afford to run my car in "G". But alas, I cannot. :(

Re: intake manifold
 

Just looked at the Guide and it shows head casting #'s for '72 and if I read it right they are: M=D2ZX-AA,D3ZE-AA,D1ZE-AA
I'm headed over to the shop in a little while and I'll see if I can dig them out.
I haven't a clue what the #'s are. I might have to wait till day light because the lighting in that building is poor. I'll post what they are. If we are lucky we can give you some class options!!

Re: intake manifold
 

I can use both heads Dave mentioned, I would be interested in getting them out of your shop and into mine once you find out what they are


My current combo has D0AE-N heads and makes big power with an illegal intake manifold:mad:

Re: intake manifold
 

1969 Boss 302 had 2.23 intakes.
