THE latest edition of Australian Muscle Car Magazine shares a few untold stories from one of Peter Brock<\/a>\u2019s most unlikely Bathurst 1000 triumphs.<\/p>\n

1975 was supposed to be a rebuilding year for the future \u2018King of the Mountain\u2019, after being dumped by the Holden Dealer Team at the end of the previous season.<\/p>\n

Instead, he claimed all three major touring car enduros \u2013 headed by his second \u2018Great Race\u2019 win alongside Brian Sampson \u2013 driving for privateer Holden squad, Gown-Hindhaugh.<\/p>\n

\"\"<\/p>\n

The cover story of AMC Issue 152, penned by veteran journalist and Brock confidante David Hassall, takes a deep dive into Brock\u2019s year in exile with new insights offered by Gown-Hindhaugh mechanic Bob Gracie.<\/p>\n

One of them shares one of the yellow and blue Torana\u2019s speed secrets \u2026 and how he and Brock nearly blew themselves up trying to execute it.<\/p>\n

Brock arrived, one day, at the team\u2019s Box Hill workshop with two big tins of chemicals that, when combined, created expanding foam.<\/p>\n

The trick was one he\u2019d brought with him from the HDT: it would fill the cavities in the Torana\u2019s bodyshell and make it much stiffer.<\/p>\n

Except there was one problem.<\/p>\n

\u201cI said, \u2018Well, how much do you put in?\u2019\u201d Gracie told AMC.<\/p>\n

\u201cHe said, \u2018Well, I\u2019ve got a gallon of this and a gallon of that, so I guess it\u2019s 50\/50\u2026\u2019<\/p>\n

\u201cSo we found an empty five-litre petrol can or something and took it outside into the narrow walkway between the two factories.<\/p>\n

\u201cWe put in a cup of this and a cup of that, screwed the lid on, and just put it on the ground.<\/p>\n

\u201cAfter a while the can started expanding and shuddering, and Brock and I stepped further back into the street.<\/p>\n

\u201cAnd then all of a sudden it exploded like a fucking cannon. Just went BANG!<\/p>\n

\u201cIt wasn\u2019t just a bang, it was a cannon, and the air force was incredible. It just exploded into dust!<\/p>\n

\u201cNext thing we know, there\u2019s the police, the fire brigade, bloody everyone came down\u2026\u201d<\/p>\n

Neither of them owned up to anything; they later found out the proper ratio was closer to 10:1!<\/p>\n

The Brock feature is one of a few focused on 1975, including a look at that year\u2019s Australian Touring Car Championship season and a gallery of largely unseen pics from that year\u2019s Great Race.<\/p>\n

Wayne Negus is the focus of the Muscle Man feature, the Western Australian racer that was uniquely employed as a driver and a mechanic at different times of his career.<\/p>\n
