Dimensional differences between LSx oil pans?
-Matt
The GM LS1 crate installation guide has some line drawings with dimensions of the C5, f-body, and truck pans. I've got a copy at the house. Have to figure out what it has that is useful, verify it is accurate (you'd think it is since its from GM), and how to post it up.
But it doesn't have info on the GTO pan, the new LS2 C6 pan, the CTS-V pan, or the small truck (trailblazer & ssr) pans. Also, any new LS2 designs (GTO / SSR) would be good to document.
We should also document the GM part numbers for these pans (and the GM part # for the matching windage tray and pickups for each).

That's the plan. I'd like to see that drawing you're talking about. If you think it's useful, PM me and we'll find a way to post it.
I thought that I had read that the Trailblazer has the steering rack going through the middle of the oil pan. (Although maybe that's just the I5.) If that's the case, it's probably not very useful for conversions.
John,
I'll see what I can find.

I think the trailblazer pan has a hole in it for the front axle to pass through (at least in 4wd applications). I don't know about steering linkage. Would be good to find out, wouldn't it?

I'm going to have to figure out how to get the paper copy into an electronic format so that the pretty pictures can be posted. I think I can do it easy, but you never quite know.

I don't have any info on the other vehicles that have received LSx series motors (ie. CTS-V, Trailblazer, SSR, LS2 stuff). If anybody has info about any of those, please post it up.

Lostpatrolman, that pan looks pretty interesting. Probably not very useful (for most swaps) but interesting. I think the 4wd Trailblazer is a different pan still. Anybody seen any part numbers?
How about the LS2 pans? The C6 pan looks "normal" compared to the C5 pan. Would be interested to see how it compares, and what the part numbers are (pan / pickup / windage tray / dipstick / tube).

Did some searching around on this site for any additional oilpan info (so that hopefully we can put it all in the same spot).
Here's what I found:
C6 LS2 Oilpan. Part # 12581810.
See pics here: Link, see post #23, Posted by KJ @ SDPC
Trailblazer 4WD Oil Pan. Part # 12579723. Should be front sump, with a hole for the axle shaft to pass through the pan. Haven't found any pics yet.
CTS-V LS6 Oilpan. Part # 12577901. Should have a rear deep sump (compared to the vette pans at least). Haven't found pics of it yet.
I also don't have info on the corresponding oil pickups, dipsticks, etc.
If you've got any of that, please post it up.
