A question about Holdens

OK I know slim to none about Holdens. Although, I am interested for weird reasons. I don't remember very well so I have a question. Are Holdens cars with Ford bodies but different motors. Or Ford Motors with different bodies?? Or neither?? I can't remember and wish to learn. Please post here with any helpful info..

I am a stupid yank that knows nothing about cars outside the states, only I hope to rectify that.

Holdens and Fords are two companies all together. visit www.holden.com.au n also www.hsv.com.au (hsv been Holden Special Vehicles). But in short Ford and Holden are rivals here n australia.
