HK Monaro with 615ci Big Block - NA Monster!

WHEN it comes to cars that are the full package, it is hard to go past Brett Armstrong’s awesome ’68 Holden HK Monaro, PROHK. Despite being a full-weight street car, the big-hipped coupe has run a PB of 8.79@154mph at Willowbank Raceway in Queensland, and Brett brought it along to Street Machine Summernats 32 sporting a fresh engine poking through the Silver Mink bonnet.
“It is a 615ci Sunset big-block Chev with Dart SR20 heads, a Mark Sullins-built Dominator four-barrel carburettor and 14.8:1 compression, so we run it on E85,” Brett said.

Love the sound of n/a engines. Don't get me wrong superchargers and turbos sound good too, but there's a special place in my heart for that beautiful n/a sound.

[@totobyafrica847]

Especially the F1 V10 era. We'll never hear that same sound again unfortunately.

[@lhtorry_rpm0748]

Fuckn oath !! Can’t beat that induction noise, not that you can hear it over this monster exhaust haha. This motors coz some serious balls would be a handful to drive no doubt. Sounds wicked props to the owner on building a solid machine ✌️😜

[@sashas8168]

Love the HK Monaro......best looking Monaro of them all!

[@robmotown1]

A real hk..... big cube big block....big power. Best car I've seen in a long time!!!!

All the best muscle cars came out in 68

[@russellhall784]

Late 60s early 70s fords are my favourite but even though i could never own something gm thats real nice especially cause its n.a. and big big block. Ive also driven a wild ht back when and it was a head turner so i can definitely relate.

[@martyburgess341]

As they say. There is no substitute for cubic inches 😍

[@Apemopar]

Its called a Barra.

[@martyburgess341]

@@Apemopar the Barra just don't have the bark that a monster cube motor does

[@Apemopar]

@@martyburgess341 Bark isnt needed to win drag races these days. Times are changing.

[@nhraandnascarfanatic5907]

Fuck yeah, no need for a blower or turbo here fellas!!... even efi! Just simple honest horsepower

[@trevorholman842]

Love it 👍

Sweet car mate

[@michaelparadisis4076]

Insane Monaro-The guy interviewing the gentleman with HK is clearly not listening , repeating back incorrect info that he heard only a few seconds ago.

[@mixalis6168]

Nothing more beautiful than a HK-G

[@robmotown1]

mixalis got that right!!!

[@lanz2168]

No replacement for displacement!!

@MrKalashnik0va No shit! Tesla All the way!

[@bacon433]

Yea sure it has 1000hp but that is one straight body

[@z00m3r__9]

Fuck yes mate

[@carsbikesandbeer4925]

Yep. That’ll do.

[@shawnfoxfirth9684]

Never mind the 615 BB - I'v long coveted one of these beauties . . .Have you ever priced one ? That's in good shape .

[@i_am_tinny_man_2267]

“Big E85 carb” what fuel you running it on? 🤣

Beautiful car and sounds killer but what’s going on with the dyno figures? On the big screen it showed 5438rpm not 7 odd thousand like Brett said.

[@STREETMACHINETV]

The rpm trigger wasn't hooked up, it's taking an estimate of the wheel speed

[@bossford1966]

Just a little over 1.? Horse per cube very nice car but not blown away by the # of 🏇

[@craigm9722]

Holy shit 962 cubes...962 horsepower dude

[@MafiaboysWorld]

That car is as fucking mint as they come. 😍😍😍😍 Separate thing though at the end, 962 cubes Iain, seriously? 🤨🤦🤣😂 I'll blame the Canberra heat for that rookie error. 😝

[@Apemopar]

Next upgrade. Barra conversion.

[@alandawson8665]

[@sirtheodorethelll633]

What exhaust are they ??

[@driftozphotography]

did he say SR20 heads like off a 4cyl nissan motor or did i hear that wrong?

[@jumpintriples]

SR20 are the ported bigblock Brodix Sunset heads from Sunset Performance 👍

[@driftozphotography]

@@jumpintriples ah cool thanks

[@AB-80X]

@@jumpintriples It's not a Sunset Racing specific Bordix head. The SR20 is just Brodix 20 degree series heads.

[@AB-80X]

That bloke is utterly dense. Big E85 carn. "What kind of fuel are you running". It's a 615 cube job. "Great car mate, nice 932 cube engine". What a clown. Great job paying attention when talking with someone.

[@Veikra]

Time to turbocharge it now

[@AB-80X]

Nah. A 14-71 is what it needs.

[@chrisoh6627]

V8 gurus?? Would it lose much power and torque if it had a forward facing manifold with twin throttle bodies and fuel injection on the ethanol?
