[LEFT]Thomson was from Shepparton, Victoria. His local race track was Calder Park, a 1.61km circuit with a fairly simple layout, containing four corners, linked by two long straights, and a couple of squiggles. The front straight doubled as a drag strip. So when Thomson found a 396ci big block powered '68 Camaro drag car being sold by local drag racer Neville Thompson, he pounced. [/LEFT]
Norm Beechey held the Touring Car lap record at Calder, at 49.2sec. Thomson figured that as his Camaro could do 11sec ¼ mile times, and that as Calder was made up of two long straights, his Camaro, converted to road race trim, would be competitive. Not a particularly scientific approach, but a pretty good guess none the less.
Thomson employed Graham Ritter, of Melbourne, for a year, where he worked as Service Manager at Thomsons Alfa Romeo and Volvo Dealership, and on the Camaro, converting it from drag car to road race car. The 396 big block was good for around 520hp. Initially the Camaro was red with white SS396 striping across the nose, but then Thomson had it repainted Alfa yellow, at which point he also had the wheel arches rolled out for fatter rubber. Peter Fowler would come on board from late 1969 to help Ritter, then took over running the car when Ritter wanted to move back to melbourne.
The ATCC became a 5-round championship in 1969, replacing the single race format of previous years. Thomson raced at the opening round, at Calder Park. He battled early with Bob Janes Mustang and Alan Hamiltons Porsche, but wasn't on the pace of Geoghegan, Beechey, or Allan Moffat, who'd just imported a new Kar-Kraft built Trans-Am Mustang. So, Thomson decided he needed more power.
[LEFT]In July 1969, Thomson, along with Neville Thompson and Peter McPherson, flew to the US, and purchased a 427 crank and con-rods, a set of open chamber LS1 alloy heads, an 850cfm Holley carb, and a set of exhaust manifolds, which they somehow stuffed into their luggage. The new parts effectively turned Thomsons Camaro into a 427 L88, with power being boosted to around 620hp, and 880Nm torque. Pretty impressive for 1969. New rear disc brakes would helped reign in all that power at the end of each straight. [/LEFT]
