This one is probably pretty quick.

But with TURBO removed... So not really a Grand National motor

Yea, it sounds like it might be slower now than if they had just stuck a regular Buick V6 into it

No idea what the compression ratio is on those, but usually lower than an N/A motor.

Still might be fun to drive.

That thing has more gauges in it than the first Cessna 150 I flew in!

I thought GN’s had about 215-230 hp depending on year. Could be wrong though. I’d guess significantly lower CR than a stock Buick V6.

8.0:1. Pretty typical of the 1980’s turbocharged motors.

there was a black 914 a while back that sold here on world , had a buick V6 in it as well, nothing too special about this motor with the turbo removed, im sure its a nice upgrade power wise from the 90 hp norm, and I guess it wouldn't be hard to find a GM mechanic to work on it if needed, just still not sure why go down this road unless the person just had the motor siting around and didn't know what to do with it?

I have a NA buick 3.8 that’s built up with a lot of speed goodies. Makes all it’s power in the lower rpm range and really isn’t that fun to drive. I’m going to take it out and put in a 2.7 six with carbs that revs higher and should be a lot more fun to drive

There was a popular swap Buick aluminum V6 that made moderate power but was great for weight savings. I don’t think the GN motor was aluminum.
