Z06, Only More So

There was no Z06 available for 2005, but it was no secret to Corvette followers that one would be available in 2006. The demand was there; with 20% of Corvette sales devoted to the club racing favorite GM had no choice but to continue the tradition.

The year off was a good thing as when the Z06 became available, it was truly something special. The engine displacement was 427 cu. in. (7.0 liters), a magic number for Corvette fans that recalled big block memories not seen since 1969. The 2006 iteration was a different displacement on the Gen IV "small block" engine, not a separate family as with the C2 and C3 Corvettes.

The 2006 Z06 motor, which featured the LS7 designation, could honestly be described as a race car engine that was street legal. The specification sheet had a lot in common with what was found in the C5-R racing engine that won the GTS class at Le Mans and the 24 hours of Daytona overall. On the list was titanium connecting rods, CNC ported heads with titanium intake valves and sodium filled exhaust valves, an 11.0:1 compression ratio and cast aluminum flat top pistons.

Possibly the most impressive feature of the Z06 motor is visible from the outside by comparing the Z06 motor to any other Corvette motor. There is no oil cap on the engine cover. That's because the Z06 has dry sump lubrication, an advanced and expensive addition that consists of a separate eight quart oil tank (above) and a pump to feed the engine oil. Not storing the oil in a sump at the bottom of the engine prevents oil starvation, which can occur in competition under sustained high speed cornering. Although common in race cars and high dollar exotics, dry sump lubrication is mostly unheard of in cars costing less than $100,000. The oil tank takes the place of the battery which was moved to the luggage compartment.

Want to have some fun with your motorhead friends? Show them a Corvette C6 Z06 engine bay and ask them to find the oil filler cap. They'll probably look all over the engine, not find it and then give up. You can then point them to the rear right corner where the oil sump tank and the oil filler are located. Inform them of the advantages of dry sump lubrication and they will then have a new appreciation for the Corvette as a serious performance vehicle.
