A little bit North of Sydney @MPS2NV Mitch at https://2nvindustries.com.au/ , specialises in these cars. Also owns a 6 himself. Face book page has heaps of pics of his work https://www.facebook.com/2NVindustries/
He built my engine 7 years ago and does all the parts fitting and backs his work. Considering the car has been running 500 to 650hp as a daily during the last 7 years and still runs flawless.
Doing a forged engine isn't cheap as these engines age to rebuild them they should be sleeved or run the risk of the factory bores distorting.
People think it's buy a set of forged rods and pistons and that's it. There is so many other things that need replacing and machining that adds up especially with our dollar compared to USA where majority of the parts have to be bought from with shipping costs. He has done plenty of these engines that get thrashed around circuits etc. and they drive home after it. Once it's done right it's a good investment that lasts for years.
