January 2000 VK Commodore with a hefty Chev punch Theres no denying that early model Commodores are making something of a comeback these days, especially the VK of 1984/85.
All sorts of parts are readily available for the early model Commodores, and many enthusiasts find the all up cost of a restoration project can be less than the purchase price of say, a brand new VT. Get the restoration right and that old VK could go as hard and handle as firm as the latest VT. Barry in Perth certainly likes the look of the older Commodores, but a 350 Chev in a VK is a little unusual. The 1985 VK arrived in Barrys hands with the Dart headed, four-bolt mains 350 already on board, utilising a kit from the renowned Castlemaine Rod Shop. But if you think that the conversion would have been a relatively straightforward affair because the donor and recipient are both from the General, think again. The starter motor had to be shifted to the other side for one thing, while some careful routing of the plumbing of the extractors is required. Rounding up the ponies The proprietor of Active Automotive, Eddie runs a 10-second SL/R 5000 Torana on the strip and is involved in numerous performance projects, many Commodore based.
The original Chev crank and X rods were retained, after receiving the usual balancing, shot peening and re-sizing work. With the barrels honed, Hypereutectic pistons went in and the compression ratio is said to be, "at least 10 : 1" Those Dart heads now play host to some top quality valve gear components, while the cam itself started life as a solid Bracketmaster. Not surprisingly, the camshaft is an area of on-going development and by the time you read this, it will probably have been changed again! Induction is achieved through a match ported Victor Junior intake manifold with a 650 vacuum secondary Holley on top, although this too is soon to be changed, probably to a 750 double pumper at least. But wait theres more! And just as we were putting the final touches to this story, word came through that Barry had spent some serious money on a new set of extractors. The old ones were in the car when Barry bought it and were, to say the least, long overdue for replacement. Of course, the Turbo 400 tranny has been built to handle the increasing power, with a stage 2 shift kit and 3,000 rpm Dominator convertor. From the back of the 400, a custom 2" tailshaft then runs out to a 3.5:1 Salisbury LSD. Elsewhere on the undercarriage reside fully rebuilt VK discs on all four corners, not to mention Monroe gas shocks and Lovells springs.
The car is clean, neat and straight, with a fully re-done interior and the original Capricorn Green paintwork re-applied. Much of the work had been done before Barry bought the car, but a fair bit of it was in need of tidying up and is only now coming good. In fact, the amount of hard earned currency spent on this VK only became apparent when Barry loaned us all the receipts for the vehicle to help with this report. Wed probably run out of server space if we tried to list everything that has been replaced, repaired, upgraded, changed, re-vamped ... we even found receipts for individual nuts and bolts !! The future is clear for Barry now though, and its all about performance. Once the power package is fully sorted, itll be onto the strip and hopefully some decent numbers will result. 12s would be good, but 11s would be better - and thats not being considered unrealistic either. Makes you wonder what the VT will be doing when it reaches Sweet 16
