Shaun Scerri's blown HQ Monaro GTS

Shaun Scerri's blown small-block Chev-powered Holden HQ Monaro GTS

This article on Shaun's HQ Monaro GTS was originally published in the July 2016 issue of Street Machine

“THE build on my HQ took about four years. It started life with a 253 and four-speed combo, but that got boring real quick. The power wasn’t there, and I wanted to drag race. So the diff centre and housing were the first things to get sorted, and from there, installing the rollcage was the kick-off for a rebuild, including a full fuel system and trans swap.

The new engine is a blown 400-cube small-block Chev with a Dart rotating assembly, solid-roller cam, AFR heads, and an 8/71 Blower Shop blower with two 750cfm E85 carbs.

The full-manual three-speed Turbo 400 trans handles the 900hp with ease, but the 8.5-inch Center Line rims hate it!

Both the engine and trans were sorted by MDT Race Engines & Autos, while Brame’s Paint & Panel in Ballarat painted the car. Special mention has to go to Daniel Collings Automotive in Daylesford; without his help this car wouldn’t be finished.

Now that MENT1L is on the road, my favourite thing is to hear the blower lope when it’s idling in traffic.”
