Re: Performance mods on AU
you can add things like 1/2 heat spacer to inlet manfold as used el gt 5.0ltr ,this does give you a little more .roller rockers increase performance without changing camshaft profile but they do take quite a bit of setting up ,ie they are usually provided with spacers to get correct lash ,this is the time consuming bit .high flo cats should be considered also (no point in getting it in if you can't get it out .)piggy back chips from aftermarket cost a lot & do little .for more information on these mods you can contact neville johnson @ wayne phillis ford (adelaide) on 08 83875777 .a friend of mine has all of this done on au fairmont 5.0ltr & it has acceptionally long legs & grunt to boot .
