LS7 = dry sump....info? anyone have any info (pics would be even better) of how the LS7 will be doing its dry sump oiling system? It should be able to bolt onto the LS1/LS6 which would open up high RPM.

i think i heard that the system uses an internal pump, so there will be nothin hanging off the block. there are a few convertions for car over here (uk) that use like a radial 5 stage pump where the orignal was (i think). should imagain it will be something moduler.
good question though, be nice to see it!
thanks chris.

I've heard that the LS7 has a longer crank snout to accomadate the pump, and of course a different front cover. If the longer snout is necessary and for real. We're bumed. Any one know for sure?

Yes, it is a longer snout on the crank and a different front cover. It would be necessary for a retrofit. We have an external dry sump kit if you're interested.
The LS7 dry sump system is integral to the LS7 engine (block).. you can not fit it to an LS1/2/6 engine.. diff pump and cover as well.
You can see it here when I did the LS7 build..

You can see a pic of the huge double impeller pump on the first page.

So it's official,
We're bummed.
I'm rebuilding my '01 vette block this summer, and I wanted to stay away from an external pump, dry sump system.
Is there any reason that anyone would advise against using the LH6 pump in my LS1 rebuild? Is there any reason not to port the exit of it like I would a normal LS6 pump?
Thank you in advance to any of you "in the know."

LS7 pan
LS7 crankshaft (24x reluctor, rebalanced)
clearance the block for 4.000" stroke
LS7 oil pump
LS7 crank gear
LS7 front cover
ATI damper custom modified by Katech to run your LS1 front drive
UMI AN oil pan adapter
custom AN lines
LS7 dry sump tank, possibly modified to fit
Katech dry sump valve covers
At this point you're increasing displacement so you need to decide if you want to use our 4.125" LS2 block and have a 427, or just buy an LS7 crate engine anyways so you have the cylinder heads. If you're interested in retrofitting a LS7 into a C5 we can help you there.
