G'day from W.A.
 

.... that's Western Australia fellas , not Washington !

I am a complete newbie to LS motors, I plan to fit one in an early model Holden over here next year and want to learn a bit about them , what parts are used from what motors etc. I am also visiting the USA next year and need to have a shopping list before I get there so I can fill my suitcases while I have the chance. I have a couple of Chevies (46 Fleetline Aerosedan and a 57 sports coupe ) plus a couple of early Holdens in my toybox

Welcome to the site. Your on a good site for info & LT1Swap has great electrical info.

How popular are chevies down there?

Welcome

VERY popular mate, there are heaps of them here now . They were sold new RHD but we only got 4 door cars and there werent many around because they were very expensive to buy new, nowadays its so easy to import them there are more American cars then Aussie ones at most events !!!!

I imported my '57 about 10 years ago and it was a real PITA to get all the paperwork etc done, my '46 I imported in 2011 and it involved filling out 1 form and a phone call to an importer :D
