Sorry guy'*, shoulda mentioned he lives 2 hours away and the majority of the time i see him is at Milan Dragway in Milan, MI. Busted too many times in H.*. to street race. But back then i drove a 72 Riviera 455BB that was far from stock and far to fast for a 16 yr. old!

Expert Gearhead
I love these threads, especially on a 3800 biased site 
Toasted, I don't consider my 4.0L Aurora slow, its not as fast off the line as the blown 3800 but it all depends on what you are looking for.
The 4.0 DOHC engine delivers even power across all power bands with its 250 bhp and 260 ft/lbs of torque, the transmission has a better gearing ratio, smoother shifts and the 4T80E is a solid tranny. The all aluminum engine properly and evenly distributes heat thru the block all controlled by a stock 180F thermo.
I've raced a stock-looking 92-95 SSEi on the hwy late at night, I teased the kids (they knew what they had), and couldnt keep up..period, a stock 3800 cannot deliver continual HP and tq at 5000+ RPM like the 4.0 can.
The downside..by far is the exhaust, its choking....it needs opening up.
As for the 3800 (stock of course) it is definitely faster off the line, I own a blown 3800 and I can easily tell the difference, you're also dealing with a very uneven power band at low RPM. I tried to keep up with Sol on the hwy in Michigan, and due to his impressive modifications, I couldnt. If he was a stock GTP, I feel it would have been a different story.
Who knows how long it would have taken my speed limiter-less Aurora to catch up to his car.
The 4.0 was never intended to have a wide aftermarket therefore you have big limitations. There is a lot of good information on the 4.0 L out there, modify a V8 Aurora engine....I wish it was possible
If you want a bolt on set of go fast mods, get a 3800 SC.

A.J. Foyt continued Ransom Olds' record-breaking tradition when he drove the experimental Oldsmobile Aerotech engineering research vehicle to a world closed-course speed record of 257.123 mph in Fort Stockton, Texas, in August 1987 with a turbocharged Quad 4 engine. Five years later, a team of Oldsmobile drivers set 47 speed and endurance records with the Aerotech powered by a prototype Aurora V8 production engine.
On January 4, 1996, Oldsmobile General Manager John Rock launched a new era for GM'* Rocket division when he announced that Oldsmobile would design and develop a racing version of the Aurora V8 to compete in the Indy Racing League in 1997.
"There'* no better way to celebrate Oldsmobile'* 100th birthday than to showcase the Aurora V8 at the Indianapolis 500," said Rock.
The IRL Aurora V8 went from the drawing board to the winner'* circle in record time. One year and 21 days after the program was announced, Oldsmobile scored its first Indy car victory in Orlando, Fla., on January 25, 1997. Smaller, lighter and more powerful than its competition, Oldsmobile quickly became the engine of choice in the IRL.
The IRL Aurora V8 is as dominant in its era as the Millers, Offenhausers and Chevy Indy V8s were in their heydays. But unlike these purpose-built racing engines, Oldsmobile'* Indy car engine has strong links to its production counterpart.
"The Indy Racing League provided an opportunity for Oldsmobile to compete with the same type of engine that we sell to our customers," noted Aurora brand manager John Gatt.
In five seasons of IRL competition, 98 drivers representing 63 teams have raced with Oldsmobile engines that are based on the design of the production 4.0-liter Aurora V8. Sixteen independent builders have prepared Oldsmobile IRL Aurora V8 engines, and nine have won races.
"When GM Racing started this program in 1996, we never expected that the IRL Aurora V8 would achieve such a dominant position in Indy car racing," said Joe Negri, IRL/Road Racing Group manager. "From the first day, our focus was on performance, reliability, durability and customer service. To win the Indianapolis 500 and the IRL championships five years in a row is very gratifying."
Oldsmobile will symbolically pass the baton to Chevrolet, GM'* new standard bearer in open-wheel racing, at the start of Sunday'* Chevy 500. Two pace cars - an Oldsmobile Aurora and a Chevrolet Corvette - will be driven by Indy car legends Al Unser Sr. and Johnny Rutherford. Oldsmobile will lead the final parade lap and then Chevrolet will bring the field to the green flag to signal the start of a new era in Indy Racing. Chevrolet will introduce its new Chevy Indy V8 engine at the start of the 2002 season.
Oldsmobile'* motorsports program has traveled a long and winding road from a Florida beach to the daunting corners of Texas Motor Speedway - with championship trophies marking the milestones along the way.
THE AURORA RECORD
Oldsmobile'* IRL Aurora V8 engine has competed in 50 Indy Racing League events since its introduction in January 1997. The following is a summary of its Indy Racing record to date:
Victories: 48 of 50 (96%)
Pole Starts: 50 of 50 (100%)
Fastest Laps: 46 of 50 (92%)
Laps Led: 9,708 of 10,175 (95.4%)
Miles Led: 13,473 of 14,108 (95.5%)
Total Racing Laps: 185,524 of 198,774 (93.3%)
Total Racing Miles: 259,595 of 278,963 (93.1%)
Starters: 1,203 of 1,299 (92.6%)
Finishers: 710 of 755 (94%)

i just feel that the 1/4 mile numbers that i have seen people posting on www.auroraclubna.com are quite dissappionting, with or without the autobahn package. I like how it performs, i like how it drives, but for 250/260 numbers, it just doesnt put down what i think it should.

The L67 is an engine built for stoplight racing. The 4.0 is a highway engine. That'* the way I see it.

The new 4.0 seems to be just as tame as the push rod version. They feel nutless

yea, i ask that because my mom'* trailbalzer is one fast vehicle. For a 5000 suv that thing moves effortlessly. How does an L67 compare to one?

L67 would destroy the Trailblazer. Particularly right off the line. Despite being nearly 4000 pounds in street trim. The L67 is too damn torquey for nearly anything out there off the line.
