Luis BRW,
I've been doing some extensive research through some contacts I have in Central America but it seems the Omega with the inline 6 was not available there. So I am persuing a source I have in Argentina and am attempting establish a Brazillian contact.
I did find something really interesting half way around the world in Australia though a 3.3 liter inline 6 From Holden . . . . .
http://www.myholden.com/images/toranas/uc/sarsha/pic6.jpg Sure looks like a Chevy L6 doesn't it ? Except for the distributor location.
How about an EFI version . . . .
http://holden.itgo.com/vk.html THe EFI motors are a 12 port head design I believe. Veeeeeery interesting Huh?
I'll keep you posted on the South American stuff if and when it comes along.
