Dry sump?

[dshannon]

Been a lurker here for awhile, waiting to start my swap. I got to thinking today. The corvettes have a dry sump oil system in them, so why can't we?

depending on the clearances, this could solve everyones oil pan clearance issues. I drive a 98 Jimmy, 4x4, so my eyes and ears are always open to possible solutions to oil pan and header clearance issues.

What does everyone think? Can it be done?

i think it still wont fit the 2wd/4wd chassis without modification. i dont remember it being much shallower than a normal vette pan.

to be more precise the ls7 has a dry sump but I dont know about the ls9. cost is the one concern that was mentioned the other one is space. the dry sump has a good size resovior that takes up a fair amount of space. I have seen some people cut down and reweld them up but you lose some volume by doing that. the other thing is they need an extra oil pump in some case they use two three or four extrenal pumps on some systems. there is no resean it cant be done but even after figuring in the cost of a custom oil pan the dry sump still cost double or not more of the cost.

Both the LS7 and LS9 use basically the same dry sump hardware.
Yes, you can run an LS7 dry sump on an LS1/2/6 or any other GENIII/IV block.
Here is what I think you will need...
1) Plug your existing dip stick hole in the block
2) LS7 pan and windage tray (and adaptors for aftermarket oil lines)
3) Custom oil tank and lines
4) LS7 crank (or an aftermarket crank with correct snout length in stroke of your choice when/if they become available)
5) 24x reluctor wheel installed on crank
6) LS7 crank timing chain sprocket
7) Early style (1X) LS2 cam sprocket and compatible chain
8) LS7 oil pump
9) LS7 front cover with sensor and LS2 style adaptor harness
10) LS7 Harmonic balancer or custom equivalant that does not yet exist.
Note that the LS7 harmonic balancer only lines up with C5, C6 and CTSv accessory drives. All other drives require either custom brackets or a custom balancer built specifically to counter the longer LS7 snout offset.
The cost of that hardware would greatly outweigh the benefits for the average S10 Swapper.
The reservoir averages about $1,300 on Ebay
There are after-market kits, but, you are still looking at $3,000+

The Corvette GS has a drysump ls3, correct me if I'm wrong, you could use the crank, oil pump, balancer off that. It has the same stroke as the ls1 and I believe all the journals remained the same size. It would need a new reluctor wheel pressed on, but it would be the easier route than custom billet crank .

I agree, the crossmember would need to be cut much like a LS2 pan would. The pan is not very shallow.

What, might I ask, would make you want to go such a route? I doubt an S10 is cable of G forces warranting the use of a dry sump. I will admit it would be cool to pull it off.

It is shallower but the cost of it offsets purchasing everything to convert...The LS9 has a dry sump with oil cooler built in but again cost and fitment on that one..

Wow, thats a lot to take in. I was just curious if it would solve the myriad of clearance issues that plague the s-series. I guess not though since I would still need to notch. Thanks for the info folks, its good stuff to know.
