Don’t judge a book by its cover – this VK Commodore skid car may not be a genuine SS, but it does have an unusual HDT performance pedigree.<\/p>\n

This article on Steven’s VK Commodore was originally published in the Feburay 2016 issue of<\/em> Street Machine<\/p>\n

YOU’D be forgiven for thinking Steven Schultz’s VK Commodore is just another HDT Brock SS mock-up. However, it actually does have some bona fide HDT DNA. A motor mechanic from Port Lincoln in South Australia, Steven stumbled upon an interesting piece of Holden history when he swapped his VS wagon for this VK sedan several years ago.<\/p>\n

“The car isn’t actually an SS,” Steven says. “It’s an SL Commodore but it went back to HDT and had the 134 pack installed.” For those who aren’t up on their HDT terminology, back in the 80s the 134 pack involved the retrofitting of leftover Brocky performance parts to an otherwise stock five-litre V8 car – kind of like a factory mock-up.<\/p>\n

$\"Holden$ <\/span>Steven drove the HDT half-caste around as his daily for a few years, but as the story so often goes, one thing led to another and the car was pulled apart for an 18-month rebuild.<\/p>\n

Staying true to the Lion-hearted heritage of his ride, Steven built a new engine based on a Holden V8 boasting 304 cubic inches. It runs a stock crankshaft rotating in a set of King bearings and is fitted with stock VN-style rods wearing Hypatec 10:1 flat-top pistons and Hastings moly rings. The crank assembly has been fully balanced and is kept lubricated via a JP standard-volume oil pump drawing from a High Energy sump, while oil temperature is managed by a cooler with fan hidden in the left front inner guard.<\/p>\n
