Brock’s true Bluey

rods, heav­ier L34 valve springs, Crane roller rock­ers, a lumpy Crane camshaft, Rochester four-bar­rel carb, matched in­let and ex­haust ports, dou­ble-row tim­ing chain, light­ened fly­wheel, HM head­ers and Lukey muf­flers.

All up it pro­duced 196kW at 5200 revs and 418Nm at 3600 revs, an in­crease of 19kW over the reg­u­lar Holden V8 with equal torque.

Back­ing up to the new en­gine was a stock Holden M21 four-speed man­ual gear­box.

Tested at the time, the VK Group A would reach 100km/h in about seven sec­onds and cover the stand­ing 400m sprint in 15sec.

Un­der the Group A rules Holden had to pro­duce 500 cars be­fore it could race it. Th­ese were built on the Holden pro­duc­tion line and shipped to Brock’s fac­tory in Port Mel­bourne for com­ple­tion.

Though the cur­rent fi­nan­cial cri­sis has caused clas­sic-car prices to soften, the Brock cars are hold­ing up rea­son­ably well and should steadily in­crease in value.

Spec­u­la­tors are ad­ver­tis­ing cars for $150,000, but look for a deal in the $80,000-$100,000 range. UN­DER the Brock skin is a Holden Com­modore that is sub­ject to the same af­flic­tions seen in reg­u­lar Com­modores. Look un­der the bon­net for oil leaks around the en­gine and power steer­ing.

In­side, look for wear on the light blue trim — it doesn’t wear well. Check the dash pad for cracks and dis­tor­tions from sun ex­po­sure.

And make sure it’s a gen­uine Group A model and not a fake. body strength and crum­ple zones in a crash. Driv­ers had to rely on seat belts.

But for its time the VK Group A did have quite good ac­tive safety with its re­spon­sive han­dling and good-sized disc brakes. WITH a highly tuned V8 un­der the bon­net the VK Group A is never go­ing to be a fuel miser, but fuel econ­omy is some­thing few of its own­ers would care about.

The VK Group A is a sunny Sun­day car — it’s not likely to be driven daily — so fuel con­sump­tion is not much of a con­cern to those who own one.

It re­quires a high-oc­tane fuel. Un­less it has been mod­i­fied for un­leaded, will also need an ad­di­tive.

Ex­pect to see fuel-use fig­ures of 15-17 litres/100km, but it de­pends on driv­ing style.
