Default LS6 Accessory in LS7

I've heard that the LS6 accessory drive bolts onto the LS7 motor no problems. Is this true? I'm wondering because i have an LS7 water pump i'd like to sell off an LS7 crate motor.

Until today that a friend told me his LS7 water pump had gone bad and an LS1/LS6 water pump holes didn't match up.

Default The same?

Did you find out if the accessory brackets and such would bolt up? I have the opportunity to buy a LS7 long block for pretty cheap.

which holes did not line up?

The water outlets moved during C6Z production but what I'm finding it should bolt on.

Anthony @ LG:


2004-2008 water pumps should be the same no matter which model of Corvette they were on.

2009 they changed not only the thermostat but also the upper water hose location. ZR1's use a completely different pump assembly.

So your saying that without a reasonable doubt I could bolt my LS6 accessory brackets from a C5Z on the LS7?

LPE lists the accessory drive as LS1/2/3/6/7 compatible and seems to be verified by other sources.
