Looking for an engine

[SterioDesign]

alright,

so i blew my engine like 3 months ago.... ever since ive been looking for a used one and still havent found anything... im located in new-brunswick canada and have been looking all around Canada and there's just nothing

i got a mazda 6 gt 2004 v6 3.0 standard... there's a bunch of automatic engine but i guess it won't fit... so im really tired of this and i dont really consider a rebuilt as an good (i was driving on the highway and my headgasket cracked or my prestone pipe broke... anyways we're not sure what happen but the engive overheated really bad and it died) so since it was overheated and all i dont think i should rebuilt it... maybe i could? but i dont know?...

so yeah... i know the duratech is used in other car but i imagine its not necessarily the same mounts and all?

anyways i really dont know what to do else than wait and wait but im getting sick of it... maybe you guys could have suggestions, thanks
