Hi I'm new to this page, I'm looking at buying a Ford Falcon and want to get around 600 out of it. I am unsure what brand of parts or what needs to be upgraded do I need to do any forged internals ? I've heard the transmition input shaft needs to be changed, new valve spring 4inch exhaust, better intake system etc. Which brand of parts would be best to make this power ? If possible I would like to do this on 98 as it's easier to get for me. Information would be highly appreciated.
