New Zealand racer Barry Algie spent 10 years turning a burnt-out HT Monaro into this monster Sports Sedan

WHEN Kiwi Sports Sedan legend Barry Algie wanted to build a race car out of a toasted HT Monaro nearly 40 years ago, it was always going to be an insane machine. His brothers, Ian and David, are well-known for their own Sports Sedans, so Barry’s HT was destined to be an extreme piece of kit.

Having grown out of Improved Production class racing after the infamous 1972 “supercar scare”, the appeal of Sports Sedans was simple. Limited regulations meant speed and horsepower were huge, making them blindingly fast and spectacular to watch.

But it was a long road for Barry to build the monster you see here, as he explains. “It started in 1975 when I bought it as a burnt car,” he says. “It was always intended to be a race car. It had been in a fire, but I sandblasted it and repaired it as I was a panel beater at the time. The roof was like a fishbowl in the top!”

However, his awesome skills didn’t stop Barry experiencing the same issues many face when trying to screw a car together. “It took me nearly 10 years to build it, and I’ve had it going for 30 years now. There were a few late nights, and the money was an issue, too. If I didn’t have the money I’d just stop until I got it.”

While there isn’t a cheap way to go racing in a national series, Sports Sedans are even more expensive than other tin-top classes, given the huge amount of freedom when it comes to setting the car up. This saw Barry go looking for raw materials in the strangest of places.

“Air New Zealand was throwing out floorboards from a Douglas DC-10 jetliner, so I salvaged them and made the [rear widebody guards] from them,” he says.

Apart from hiding those steamroller 13-inch-wide rear wheels, Barry needed the fat haunches to keep the 600hp mechanically injected small-block Chev cool. As with many early Sports Sedans, the fluid coolers are actually rear-mounted.

“The radiators are in the back because of weight distribution and aero reasons,” Barry says. “You don’t want them in the front because you have to do something with that airflow, and the car will go skyward with the radiator in the front.

“I made the flares to get airflow through to the rear-mounted radiators; they’re pure function. It had other flares originally as I was trying to pull air through the cabin, but they weren’t very successful.”

I got a Formula Pacific wing and scaled it up for our cars.”

“I made the whole front end myself. It’s a live front end with no stub axles or anything,” he explains. “You can see the tyres are worn evenly; it works well. It’s a nice car to drive. You could put a complete novice in this car and they wouldn’t come unglued.”

One reason for the heavy chassis modifications in the class was to improve weight distribution, something Barry took care of by not running a traditional gearbox behind the engine. Instead, he looked to a legendary Le Mans sports car for answers.

“The five-speed transaxle is based off a Ford GT40 ’box, made by ZF. That is also for weight distribution, plus this car has a De Dion rear suspension.”

The engine is a rip-snorter, built at home by Barry. “I call the engine a 348. It is a 4.125-inch bore, 400-cube Chev block with a 327 crank, so that gives you the revs of the little engine and the power of the big engine. It revs good!”

With spark supplied by a CDI from an Indy Car open-wheeler, Barry estimates the package will make a solid 600hp. More importantly, it will last the distance while being wrung out around the very fast Pukekohe circuit in a main feature race.

And with a bunch of thundering widebody V8s, we can understand the appeal!
