Why put it on a V6, why not put it on a real engine? Then you would REALLY have something!
Corporate mileage average. They needed to sell 4cyl and 6cyl cars to offset the gas guzzlers. A gnx driving moderately gave good gas milage

Hmmmmmmmmmmm, OK, I see------------I guess that's why I replaced the tired 350 in the 51 Chevy with a built 2x4 389.
And that's why I built a W30 spec 455(468) for the Cutlass.

No, brute power from big displacement engines are not over in this neck of the woods.

Re: Modern Grand National - Yay Or Nay...

Fact is, the Buick GN's turbo V6 was faster than ALL of the other "brute power from big displacement engines" available, given the Federally mandated fuel economy and emissions standards at the time.

The huge leap in collector value of those cars in the last ~5 years would suggest that the Gen-X'ers who grew up in the 80s desire them as much as the Boomers love their big block muscle.

There will always be big block big cubic engines for our cars . I'm presently putting a Mark Jones 496 in my 66.

But Toofastforyou was pointing out no new cars will be 454 or anywhere near that displacement . Why would they when you can get 6 to 700hp out of a sub 400ci engine and get 25 mpg

That is YOU. Not the manufacturer. YOU don't have to answer to fed govt regulation. What you do with it after you purchase it is your choice (within reason of course - it still has to meet whatever requirements that make it "road legal"). The mfg doesn't have that luxury. They have to meet MPG, emissions, and crash worthiness standards by LAW. Every engine must be EPA certified for the platform it goes into. That is not a cheap or trivial process. That's one of the main drivers why GM dropped having dozens of engine models across every brand and standardized on a few "corporate" platforms (predominantly Chevy). That's why the big V8s disappeared from passenger cars in the 70's as soon as the earliest emissions requirements went into effect. That's why even the beloved 350 gave way to the 267 and 305 (a friend had a '78 Malibu with the 267 - it was slower than my '93 Gutless Supreme 3.1v6!).


Besides.... many of us live where the roads aren't straight as an arrow and flat as pancakes and having less weight up front makes for a more enjoyable spirited drive around the twisties.

Re: Modern Grand National - Yay Or Nay...

I had the opportunity to buy a new Grand National in 1987 but instead went with a Firebird Formula. A few years later, I took a GN for a test ride and i was shocked over how fast it was. I bought a used 86 GN and did a total restoration adding a few performance pieces along the way. I became friends with most of the other GN owners in town and we would work on each others cars and discuss ways to make them faster. Running in the 11s was no big deal. When my GN was done, it was fast and the sound the turbo made spooling up was incredible. Unfortunately, mine was stolen and so were four of my friend's GNs. Only one got his back.

Re: Modern Grand National - Yay Or Nay...

I had a 1984 GN in 1985-86. It was the 1st year for them and they had a few differences. They had 10 spoke alum wheels that I think looked better than the later chrome wheels and had better looking seats with cloth and leather centers. It was a lot of fun to drive but hard to handle in the snow. Everyone knew what a Monte SS was but no one knew what a GN was. I always had to argue with people that is was a Buick. This pic is not the one I had.

Yay or nay?

That thing is pure ugly!

When I works, I works hard.
When I sits, I sits loose.
When I thinks, I falls asleep.

Re: Modern Grand National - Yay Or Nay...

I think it's sharp. I would give it garage space if it doesn't end up being a 60K + car.

Re: Modern Grand National - Yay Or Nay...

Nice concept, GM probably is as willing to build this as well as a new El Camino, and sell it at a reasonable price....sure,....fairy dust. Got to drive a 87 GN, very impressed, strong medicine, now that I could afford to buy one, they gave up making them. Have to respect a good running turbo car, quiet, doesn't draw John Law out of the donut shop like the sound of a 500+ CID BBC at full song will. For now, guess I'll have to be satisfied with my BBC.
