AUSSIE x-flow parts for USA...

[stagen]

Im not too worried about the manifolds seeing as the plan would be for custom pieces any way (EFI, future turbo) Really it'd be nice to get a complete head + the valve cover, although with the little research Ive done there seem to be alternative parts to use for the heads internals. I also saw on AussieSpeed that they had valve covers and some hotter cams so I may be covered there. Im talking to a guy on the Aussie ebaymotors that has a complete engine for sale. I asked if he'd be willing to separate the head and ship to the states. now its a matter of figuring out the cost. Just so I have something to compare to, what would I be looking at spending on a crossflow head thats already in the states? (project part outs ans whatnot)

Im watching from the side lines and I have to say WHY would you want to apply the alloy head to a US 200, when it would be FAR easier to just get a 250 crossflow in its entirity.
The 250 will rev OK with the turbo or improved cam etc if thats your worry, and they are relatively abundant, Ive got a 200ci crossflow which I had to search about to get, but 250s are much easier to get, and have tonnes more torque. I cant think of any reason why you would stick with the US 200, the crossflow 250 would run rings around it, and the trouble to fit the crossflow head to the pre crossflow block is just too great, nobody here would give it a moments thought.
Sounds like you wouldnt pay much extra to a a full engine into USA anyway.
You might also like to consider that the OHC engines, they are dirt cheap here, and consideably better than the crossflow, you can get the VCT AU 4l engines for about A$600 from wreckers yards. These things a bulletproof just like the crossflow, but have a MUCH better top end.
All food for thought.

Just so I have something to compare to, what would I be looking at spending on a crossflow head thats already in the states?

qty 1 used cross flow head with ~56cc chambers, runners and chambers unmolested. Carby head w/out injector scallops.
qty 6 used intake valves, qty 6 used exhaust valves. stock size
qty 12 stock valve springs
qty 2 head gaskets. One similar to ACL, one cheaper.
qty 1 NIB Crow #14650 hydraulic flat tappet cam. 230* @.050, .520" lift, 113*LSA.

It would take about $1k for me to sell it all, if I post it for sale.

You'd still have to source gaskets, intake, headers, rocker cover, valve train, lifters, adequate valve springs, etc.

AFAIU:

1) Crossflow head can accept 351M/351C/Boss 302 Valvetrain; aftermarket parts readily available stateside.

To go oversized valves: cut the head down on some 2V Cleveland Intake valves to 1.84", 1.6" Chebbie exhaust valves.

2) Internal parts are stateside available with US block; not so with Oz.

3) Oz block and US transmissions don't mate. An Oz trans/Oz motor would help but you folks sit on the wrong side of the buggy. X_flowFairlane had an adapter made not too long ago to mount a US T5 to a Oz block, I believe.

4) SBF T5s, SBF C4s, SBF AODs performance pieces are plentiful stateside and a US250 block makes them a slam dunk. A US200 makes little sense, I agree. Low on cubes and requires pricey adapter to get a good manual trans. behind it. A perf. torque converter for a US200/C4 is a pricey piece too, with ring gear welded on it.

5) US250 block with crossflow head; DSII should work.

When used on a US250, you get a good flowing head with the only non-stateside available pieces that should need replacing while rebuilding/servicing being gaskets. Spark and Transmission hook-up is normal. It is similar in appeal to the CI aluminum head; good flowing head with few parts not carried at AutoZoo. However, the CI head is by far a less risky operation to install and flow numbers posted are better than what I've found for the crossflow. With patience and a plan, a guy can probably get a crossflow converted US block running cheaper than getting an Oz engine running in a car. I'm inherently stubborn with a little more time than money so I do stuff the 'fun' way.

I admit that I could be forgetting something there, please correct me if that is the case. I have yet to mod my US250 block that's in storage yet but I'm going off hours of research in preparation.


Cheers,

Clevend valve train bits do fit, but valves do not.
EFI crossflows have 1.8 and a.54 valves in them stock.
There are bellhousings for T5 here.
Mustang six has done all the work fitting this up
Now that crossflowa are getting pretty old, why not look into the Sohc or even the DOHC 4 litre engines.
Both the SOHC and DOHC variable cam engines are about $600 down here.
