And there's more.VF HSV and late Z28 extractors which need some vinegar on the heat shields to get rid of the rust stains but other than the rust are in excellent condition. Unlike a L6 say, it's impractical to tune the V8's pipes in accordance with the firing order but these are plumbed 1,3,2,4 rather than the usual 1,2,3,4 which I hope means something good because it's a more expensive way to do it. The other item is the Improved Racing crank scraper and baffle, entirely CNC machined and as light as, good enough to go on display. LS engines need all the lubrication assistance possible so oil return is vital.
