i have heard about one of these. what did they come in? got any idea on hp/tq specs? i take it that it is a 90 degree motor?

Yep. It was a 90* block .. based off of the 4.6L Northstar .. the motor was dubbed "Shortstar" .. it punched out 215hp with 230lbs torque. Had a 6400 RPM redline.

It came standard in the Olds Intrigue and base model in 2001 Aurora.

Pasted from that link:

The 3500 LX5 V6 is a DOHC engine from Oldsmobile, introduced in 1999 with the Oldsmobile Intrigue. It was produced by the Premium engine group at GM and was thus called the Premium V6, or PV6, while it was being developed. It is based on the L47 Aurora V8, which is itself based on the Northstar engine, so engineers called it the Short North, though Oldsmobile fans have taken to calling it the Shortstar.

It is not a simple cut-down V8. Although it has a 90° vee-angle like the Northstar and Aurora, the engine block was engineered from scratch, so bore centers are different. It has chain-driven dual overhead cams and 4 valves per cylinder, but is an even-firing design with a split-pin crankshaft similar to the modern GM 3800 engines. The LX5 displaced 3.5 L (3473 cc) and produced 215 hp (160 kW) and 230 ft.lbf (312 Nm). Bore is 89.5 mm and stroke is 92 mm.

The cost of building this engine was high, and it was not used in many vehicles. It was said at the time that a family of premium V6s would follow, with displacements ranging from 3.3 L to 3.7 L, but only the LX5 was ever produced. It was entirely different from any other V6 in the GM inventory, and as with the Aurora V8, production stopped with the demise of Oldsmobile.

This engine was used in the following:

1999 Oldsmobile Intrigue
2001-2002 Oldsmobile Aurora
The 3500 LX5 was on the Ward's 10 Best Engines list for 1999 and 2000.
