What the Heck did I buy?

[Bayrunner]

Fellas, after reading all of the crossflow ID Posts, I am now confused with my recent purchase and need your help.

I am the proud owner of What?

Aluminum head for sure, it has the injector notches on the intake side, it came with the banana tubes, spacer/housing for the injectors, plenum and that is it.

Numbers are. HF1 on the inside. 11yc on the front. 321 on the intake side and 06 by the water housing.

Reading the posts, HF1 heads were pre efi? The notches look like originals and not after the fact? Can someone help me out here to identify what I have and how it compares to others?

Also, What do i need to do in order to turn this into an EFI for my 200ci US build.

Thanks in advance.

I will warn you though, I will have many questions as I do not have your knowledge. I do appreciate this board and all of the fine people here.

Sounds to me like an almost complete efi setup. Did you get a throttle body?

Any pictures?

Bayrunner,

Are you the one who won the eBay auction for the crossflow from THE FRENCHTOWN FLYER?
If so, congratulations. The head is supposedly recently rebuilt and will save some $$$.

Look between the 1 and 2 intake ports to see if there is a letter imprinted on the head; this will help identify the head. If no identification letter is there, it is probably a D or E head.

If you are planning on installing it on a US200 block, here are some other parts you need to acquire:
- Crossflow cam.
- Crossflow valve cover.
- Crossflow exhaust; either stock cast manifold or aftermarket extractor (header)
- Valve regrind gasket set (includes head gasket, intake and exhaust gaskets, valve cover gasket, and valve seals).
- Distributorless ignition system with dummy drive for oil pump. The EFI intake leaves little room for a distributor on a US200 block; an EDIS system with a crank fire wheel would work. If this type of ignition system is used you would need a dummy drive from a Tempo 2.3 or OHC 2.3 (retrofitted for the 200 block) to run the oil pump.

The EFI intake is nice with its long runners. The Ausssie EFI system that came with it is crap. It used an old flapper style MAF (Mass Air Flow) system that is not friendly to hipo mods. An aftermarket system or a stock system retrofitted to the 200 would be better.

You will also have to modify the block and head for this adaptation to work. Block modifications include installing a plate on the cam side of the block at the top to seal the wider head, opening up some of the holes where the lifter rods come up through the block to accommodate the Aussie cam, and blocking off some of the water jacket holes and adding others. Head modification involves blocking off some of the water jacket holes. There was a website that illustrated this but it is no longer available; I saved the page and can send you a zipped file if you want.

Don't be despaired, this modification is possible. MustangSix was the one who figured out how to do it and runs this engine in his Locost.
Mike from Classic Inlines wrote me and said he could get a Pacemaker header from Australia, and maybe some of the other pieces.

The reason I know about this is that I have been acquiring the parts for the last couple of years for this modification.
MustangSix is definitely the man to talk to.

If there is any way I can help you, just PM or email me.

 

[Bayrunner]

Yes, I purchased the Head from Sixracer on Ebay. What a great guy. He could not tell me much about the head as he did not run it. I cannot believe that it only went for the starting price. I got lucky.

Images as requested.

Please go here. http://cgi.ebay.com/ebaymotors/ws/eBayI ... MEWAX%3AIT

I could not get them to post another way.

Now, I will take what ever help I can get from you guys. I cannot find the C or D stamp anywhere. 321 J is the only markings on the intake side.

Does anyone know which head this is. Year, CC, performance compared to other heads?

Thanks

OK... By the photos I think you have a head & manifold off an XE falcon (1982-1984). I have one of those in my wagon - it's not bad at all! You'll need to get a throttle body but I'd expect you'll get one that will fit from a junkyard - otherwise, PM me and I'll dig one up for you here.

 

[Bayrunner]

Fellas, I have a hard time with the pm stuff. Can you please pm me so I can reply back to you?

Thanks

 

[Bayrunner]

My original Question still stands.

If the head has a HF1 Stamp, is it a true efi head or not?

 

[wagon]

It doesn't make any difference. Nearly all heads 1983-onwards had the little notch in the intakes for the injector. The motor in my car (250 crossflow) was carby - I made it efi with no head mods.

 

[Bayrunner]

o.k. now it makes since. thanks


Wagon, you are the man

 

[Bayrunner]

Lastly, Opinions please.

1. do I trash the banana and go with a Ausiespeed intake with a TBI or
2. Build the banana with modern throttle body?

Also consider space for the powerplant in a 66 mustang

Thanks

Keep the bananas - easier to tune + looks trick

I have a stock EFI intake I might be parting out....going with a spare spacer I have and a sheet metal plenum to replace the stock one and the bananas. the stock TB is designed to pull across the motor to the passenger side. would take a little work to get it workign right on a LHD car. I would suggest finding a TB off something US and going with that. I have a 2.3L OHC TB off a turbo car I would give you for shipping if you want it? maybe a billet spacer and a 5.0L throttle?

you will need a fuel rail to fun EFI on that btw....


I have a 4bbl CAIN intake I might be willing to part with.

Bayrunner,

Make sure you have the head cc'd before you plan for a rebuild. The alloy heads had combustion chamber volumes ranging from 42cc to 57cc.
If installed on a 200 with stock deck height and 6.5cc pistons, the CR would range from 9.9 to 8.1.

Look between the #1 and #2 cyl on the intake port side of the head and see if there is a letter and number marked on the head (C1, C2, D, E1, E2). That will tell you what head you have and can determine what the original chamber volume was.

Did you receive the webpages I emailed you?

 

[Bayrunner]

Wagon: I will keep looking for your papers.
Rockford: Yes, you are the man
XFlow: Thank you so much. I'll keep you posted.

I looked all over the place for the casting. cannot find one. I will measure the chambers Saturday and let you guys know.

Thanks for all of your support

 

[Bayrunner]

Measured the CC on the head today. they are all between 55.1 and 55.4 cc's. Valves measured at 1.7" intake and 1.5" ex. No other Id's on the head.

Thanks for your help. Can anyone pinpoit this thing?

 

[rocklord]

From what I've been able to scrap together about the Crossflows, you have a head from an XD-XE model car and it originally had 57cc combustion chambers.

I've seen recommendations to have larger intake valves installed, about 1.84", and leave the exhaust valves stock to make the intake/exhaust area ratio around 77%

I don't know how much you can mill from these heads to increase CR.

Just some more useful/useless information.

 

[MustangSix]

No issues at all with fitting it in a Mustang. There should be plenty of clearance everywhere. The only issues might be with headers, but if you use the stock exhaust it will fit easily. I had to massage one of the tubes to get them to clear on my 66 coupe, but those headers were originally for a Cortina, I think, which is a different chassis.

In addition to the items already listed you will need lifters from a small block ford and pushrods from a 3.8 GM v6.
