Why cant i find any aftermarket intake manifolds for the 250..Ive tried to look at mustangs unlimited and NPD but i cant find one?? HELP!!

if your talking about the early us or aussie 250 the intake is cast on so you cant do anything easily to them. offenhauser used to make a couple different intake set ups for them but both require a fair bit of machine work. the aussie 250 2v head has a removable intake add you cant buy anything new for them these days. the aussie 250 crossflow head has 2 barrel and 4 barrel manifolds available for them. feel free to contact me if you have more questions. cheers

in addition to the aussie 250 2v, and the aussie x-flow, the argentine 221 me and sp engines also have removeable intakes. check out Classic Inlines Performance Parts - Home for a new aluminum head and intake for the american six. and check out the tech section of Ford Six Performance: The Web's Leading Resource for Ford Inline Six-Cylinder Engines and Cars! where one of the members there swapped a crossflow head on to a US 200 block. think it cant be done? jack did it. says it runs real sweet with a lot of power and throttle response.

of course you can adapt a x flo head on to any of that series of 6 cyl engine but why bother.? just use an alloy head aussie 4.1 L (250ci) engine. with 200ci length rods and short deck pistons they love to rev aswell.

the only problem with that is the cost of shipping a complete engine vs a cylinder head to the US.

but the ammount of work involved would be offset by the shipping cost!

as opposed to the amount of work adapting a US trans to an aussie block? remember that you will need either an aussie bell housing, or an adaptor plate. as for adapting the crossflow head on the US block, check this link out;

Ford Six Performance: The Web's Leading Resource for Ford Inline Six-Cylinder Engines and Cars!

you will find the procedure much easier than you realize. the problem jack had was with distributor clearance, but only because he was using a US 200 block rather than a 250 block which would have given him and extra 1.5"

as for the amount of work offsetting the shipping costs, i rather doubt it. remember that there is a large difference in cost between shipping a 500lb engine as opposed to shipping a 100lb cylinder head.
