so would you consider the 4.0 V8 to be fun to drive at all? The gas mileage isn't very impressive i know that.

gosh i just don't know. The L67 sound like a much better engine because it is faster AND gets better mileage. How is the L67 when it gets up into the 55-75 mph range?

the L67 tends to fall flat on its face in the upper RPMS..... you will get the 2nd gear kickdown on the highway but its not a high reving motor

Dood, seriously go drive both cars, its the only way you will get a proper idea of what the cars can do.

If you dont know what a 4.0 gets in mileage, dont assume. I've seen 36.9 mpg in my 4.0, and average 28-30 mpg on the highway. 18 average in the city.

I had a 3.1 in my 93 GP and it sucked! It had some torque off the line but past 40' feet, nothing. As for the Trailblazer with 270 (joke) hp, cousin has one and think'* he'* the ****. He ran a 17.14 at Milan and got laughed at. The 4.0 would stomp it! Anyone who say'* different hasn't raced it against anything but a stock 90hp Civic!

No offense whatsoever intended for my highly-respected Admin buddy, BUT....

I've probably driven more Bonnevilles modded and stock than anyone here. And I've also driven 3 auroras and 2 GXP'*. I've also owned a Northstar at one point myself.

And I'd have to give the stock for stock edge to the L67 OFF THE LINE.
Stock for stock edge to the Aurora ABOVE 90mph, but who drives like that?

Now considering the lack of a good aftermarket for the Aurora, the modding isn't really a fair comparison, but it'* VERY easy to mod the L67 to beat the Aurora all-around. Mild mods and the L67 is gone.

On top of that, the L67 tends to be more bulletproof (years of experience with the 3800 prove this), while the Northstar family tends to have some gray areas for reliability. These are issues you can fix, but they are issues nonetheless.

The L67 is more forgiving to work on, and should be cheaper to maintain in the long run. Particularly when you factor in gas mileage.

We can banter back and forth about how good each engine is, and where they offer plus and minuses. The 3800 is a good engine for wrenching, and modification, if thats is your game, and yes with gobs of torque it offers that off the line advantage.

I to have driven many a 3800, everything from 8-Ball to a stock LN3 powered 89 SE, a few GP'* here and a 01 Regal GS. For my perspective nothing has offered a better overall driving experience then that funny looking white car down there

But we are all biased arent we!
