Mark Simmonite's 1973 Holden HQ Monaro

This article on Mark's HQ Monaro was first published in the February 2019 issue of Street Machine

“IN NOVEMBER 2017 my HQ Monaro was treated to a full bare-metal respray in Inca Gold. Since then, every rubber, seal and clip has been replaced, along with all the door internals.

The entire car has been rust-proofed under the paint, and the interior has been treated with Dynamat along with new underlay and carpet. All the badges have been replaced, the bumpers re-chromed, and the stainless trims repaired and re-polished.

The four-inch reverse-cowl bonnet covers a Holden 355 stroker, with a VN block and Yella Terra 5000-9 alloy heads. The T400 gearbox is rated to 1000hp, matched with a Dominator 4300 high-stall and a B&M Pro Ratchet shifter with a custom LED shift light.

The diff is a nine-inch, with 31-spline Strange axles and a Truetrac centre with 3.7 gears. Solid tubular adjustable trailing arms hold the diff in place. Bolted on to the VN disc brakes are a set of 15x5 and 15x8.5 satin-finish Center Lines.

I’d like to thank Joe Zirino for the engine build; Mick (Super Mario) and Baby Jesus from Briffa Engineering; Todd from Pro Street Polishing; Jake from Static Whitewalling; Phil & Gina from Extreme Panel & Paint; and Luke and Rory from AutoSpark Joondalup.”
