Rebuilding Aussie X-flow

Post #1 by danwagon » Mon Mar 07, 2005 5:21 pm

OK the Aussie engine(esp head) sounds intrigueing- But I wonder, How difficult is it to find parts stateside to rebuild one? Was given the impression that they are metric orientated. Anybody got the scoop on this?? Thanks Dan

There's maybe some metric stuff on the last crossflows, but not significant.

People get hung up by this "spares" idea. Build an engine right, look after it, and you're as well prepared as can be. You can be equally marooned in any vehicle with unforseen delays. Best tack is to ship rebuild parts like pistons and bearings.

One very important thing is that nearly all the parts are still on offer in Australia. Aussies are friendly and willing to help.

I'd sugest you go over Jack Collins (Mustang Six's) Crossflow Chronicals in the tech section. Please consider getting the engine rebuilt in Australia before it arrives in the States.

If you don't, you'll have many long nights here going over the items which you need to source locally. It only needs one substandard part to mess up a great engine. Having siad that, the choice is yours, and Jack Collins rebuilt his. I believe his son is enjoying it now in his white Mustang!

The x-flow has a significant amount of US spec 351 Cleveland and 351M/400 bits in the valve gear that can be cut down to fit. Lifters, sled fulcrums, head bolts are the same. Valve springs can interchange with some carefull research. The oil pumps, pushrods, water pumps, and hex drive and distributor have differences which require a bit of work to allow the US parts supply bits to fit up. You have to duplicate the stock Aussie bits if you want a lot of domestic bits.

The main bearings differ in crush and thrust widths, and the timing chain has an extra link in eaxh direction, with the same aftermarket crank gear and cam set that FSSP sells. The 250 rods are same as the US ones, and rod bearings are the same but have a specified crush which differs to the Aussie xflow. Pistons are similar, but not the same.

The best thing is to go over the engine part numbers Ford lists, and check if you have enough budget.

All bits need to be rebuilt unless you have a pristine orignial part. Here's a Ford Basic Part Number list I use to jog my memory. Ford itemises every item in it cars, and keeps a standard part which is either avaliable as new old stock, or reconditioned, or brand new from suppliers.

Thanks for the info guys, was looking at ebay item -basically a 250 x-flow ready for rebuild. since i am dealing with a daily driver that i have already sunk a bunch in just in weatherstripping and and interior hdw. I'll probally settle for mild hop up on loghead-- :idea: Will a crossflow head bolt onto a yankee short block?

Be carefull if you go with the crossflow on a US 200 block. I don't really know of anyone who has actually built one of these and run it for any length of time. Mustang6 did build one but had to shelf it because of dizzy issues.

Not saying it cant be done, just do your homework and be ready for some setbacks. You will still need an OZ cam for this swap so it may make more sense to go with a crossflow block.
