Formula Ford One Cool Cat

2 February, 2024

GM hasn’t produced too many cars under the Buick marque of late, but reminiscing about how they used to is a good reason to bring Marin Leusink’s Wildcat out of the shadows
By Mat Mortimer

In the ’60s Buick was butting heads with the Mustang and Thunderbird, Corvette, Impala, and many others for eight-cylinder supremacy. 
In the Buick stable the most well-known of the marque was the Buick Riviera, a competitor in the American version of the luxury auto market and, while it was a two-door, it wasn’t squarely pitted against the popular Ford Thunderbird. Following the introduction of the Riviera in the early ’60s, Buick released another trophy car, the Wildcat. 

A Wildcat on the prowl
It’s fair to say Taupo-based Wildcat owner Marin Leusink is a fan of the big cat. 
Marin’s 1964 Buick Wildcat is a two-door, hardtop sedan, powered by 401 cubic inches (6.6litres) of Nailhead V8 engine, backed up by a TH400 3-speed transmission. 
The 401 Buick Nailhead engine wasn’t just used in the Wildcat. The 401 was the second generation of 90-degree V8 power plants producing 325bhp (242kW) and a significant amount of torque for the time — 445nM. This number was impressive enough for the engines to be used elsewhere in a somewhat different capacity. They were mounted on trolleys and used as ‘starter-motors’ for the SR-71 Blackbird supersonic jet!

Some effort required
After considering the options Marin imported the car from Arizona in 2017. 
“I wanted to make sure it wasn’t from a seaside state, to avoid too much rust in the body,” he says. 
Marin set about giving the cat some claws (again). For some reason the roof of the car had seen some filler, but inspection showed no real reason for it being there. After taking the car back to bare metal, the bodywork was done, minus the unwanted and unneeded bog to get it to the revitalised state it is in now – all stock to the 1964 variant.
The ’64 is special in that it didn’t feature the regular horizontal Ventiports like its predecessors, but instead it wears the vertical chrome Wildcat-branded hash-marks on the lower front quarter panel, setting it apart from others of the same era.

Making it purr
No project car can ever be complete on bodywork alone — even a classic such as this. 
Marin decided to breathe some new life into the Buick, boring the already capable 401 cubes out to 407 and adding a few extra touches, including TA Performance roller rockers and a super street camshaft. Crowning all this valve train work was an upgrade to the standard Rochester carb, with a 770 Ultra Street Avenger looking after the inhalation. 
Breathing out also became a little less restrictive with headers and a 2.5inch exhaust added. 
“As much as I’ve tried to keep it original in many ways, these changes all made sense at the time. The original Rochester was replaced — they do have a few issues — and I haven’t looked back really,” he says.

The finished product 
The ’Cat rolls on a set of standard wheels, with the option of a set of chrome Cragars. This gives Marin the ability to get either a hot-rod look and style, or keep it closer to how it was in the ’60s from the factory.
Either way, with all of the work put in, it’s clear the car is now back to as close as Marin could get (engine aside!) to a great looking standard Wildcat, and it may well be literally one of a kind. 
“I’m pretty sure it’s the only one in captivity, there are a few Rivieras about, but I haven’t seen another Wildcat.”

Polishing to perfection

The secret to a show-stopping finish is colour sanding, no matter which paint system you use. Even a good painter, no matter how experienced or talented — like my mate Bruce Haye, CEO at Ace Panel and Paint in Whitianga — can’t shoot to a perfect mirror finish. To get that level of perfection, you need to colour sand.
It used to be called ‘rubbing out’ or ‘cutting’, and it was done with pastes that came in cans. They worked — sort of — but the compounds really just rounded off imperfections instead of eliminating them, and they removed a lot of paint in the process. But now your new finish can be made flawless, thanks to microfine sandpapers that come in 1000, 1500, 2000, and even 2500 grit ranges, and Farecla G3 polish — available from automotive paint suppliers.

BMW’s flagship techno showcase
The supermodel 1995 BMW 840Ci is simply elegant and perfectly engineered.
BMW’s 840 Ci flagship Coupe provides superb comfort and equipment packaged in a stylish body, with grand-touring performance and surprisingly competent handling for its size.
It’s the kind of machine that stands apart from the start. When BMW first unveiled its flagship Grand Tourer at the 1989 Frankfurt Motor Show, the automotive world blinked twice. Sleek, low, and impossibly modern for its era, it combined drama with a sort of purposeful understatement. This silhouette still looks striking today, long after its peers have faded into obscurity.
Initially offered with a range of engines, the model you’re reading about is the V8 iteration, featuring a 4.0-litre eight-cylinder heart under its long bonnet and a smooth five-speed automatic at the back. It wasn’t about blistering sprint times so much as effortless velocity. There was power on tap, sure, but the way it delivered thrust felt unhurried and measured – the automotive equivalent of a deep exhale on a long drive.
