I’m a fan of the Buick V6, mainly because I used one in a front-drive Regal to add a nice tidy bit of extra change to my bank account thanks to cocky Mustang and Honda drivers around Tacoma. In production for nearly fifty years, the big six found legend not only as a great Jeep engine as the Dauntless, but as the turbocharged and intercooled little bucket of psychosis that gave Buick some surprising swagger in the 1980s, and even in front-drive form, the supercharged versions could hold their own quite nicely. Remember the outputs…the GNX mill made 300 horsepower and 420 ft/lbs of torque, and it’s the high point of factory performance. But there was a step or two further…the Indy mills. A project that Buick pursued in partnership with McLaren (what, you thought the GNX happened by accident?), the Indy V6 was a wicked little N/A beast that could absolutely shriek and when it was running right, was laying down big-boy power. In race trim, that would be about 700 or so horsepower.
Confession: I don’t pay attention to much of anything IndyCar-related. But shove this little howler in a IMSA-prepared Monza and you will have my full and undivided attention. Trust me…I’m not a fan of how GM V6s sound, but this is good. Real good.
you build them right and you can do a lot of things. our buick 350 has no problem doing 7500 rpm at all.
