273 into a 62 Lancer?

Hey guys,

I have come across a 273 commando motor, and wanted to know how feasible it would be to replace my slant six with this engine. A few things I'm concerned about (and please enlighten me to the many others!):

1--pushbutton auto trans--will I be able to use the 904 pushbutton trans with the 273?

2--Fit? Can I squeeze this sucker in there? What issues with the K member, drag link, etc will I be facing?

3--Other? Can you point me to a good resource on engine swapping?

Thanks guys!

MJ
