LSX oil pans

I recall reading that the Holley pan is rumored to be the same casting as the Mast pan. (See my previous pics.) The Holley and CTS-V pans are both very shallow in the front, with the CTS-V perhaps a bit shallower.
EDIT on 02/09/2012 - See post #451. It appears the Holley pan is based on the older RetroLSX pan, not the Mast pan. Sorry for the mistake.

for $153 to my door is my option. It is going into a 66 Chevelle that will be stock height with proboably 17 or 18 in wheels so I don't think ground clearance will be a problem, now I just need ot figure out the mounts. Any suggestions? Thanks.

It is safest if your oilpan does not extend below the frame crossmember at all. I think this forum had the story of someone running either ther CTS-V or the Muscle-car pan and hitting a raised man hole cover in a construction zone.
I mostly know Camaros (although my first car as a teenager was a 3-year old '70 Chevelle SS 454). As far as I know, all Chevys that took a SBC or BBC have similar engine mount geometry. Transdapt makes conversion mounts that will work for you. You can pick "stock" position or "1 inch" back. They sell one kit with only the conversion brackets and one kit with older-style (not clamshell) engine mounts. I prefer the safer clamshells, but those might not fit your car without new mounting holes.
I don't know if the Chevelle forum has extensive swapping info, but the 2nd gen Camaro forum certainly does. Most everything would apply to your car too. The forum is here:

Otherwise, I would suggest starting a new thread here to ask non-oil pan related swapping questions.

As I mentioned earlier, I suspect the Mast and Holley are made from the same casting. Best that I can estimate (again sorry I'm not sure), this casting is very similar to the F-body in terms of height and front clearance issues. The Holley/Mast is a safe choice to ensure that unexpected road debris doesn't destroy your engine.

Rear corner had a small lip on the seal surface that was cause by their machining.
I checked out the same oil pan at sema this year and gues what?!...it also has the same lip when it should be a flat surface.

as you all know that could cause a leak and oil pans are part of the structural integrity of the engine.
I complained about the poor machine work and after about 2 weeks of emails, they said
"engineering dept has had no leak issues and you can return it to where you bought it from"
a $400 oil pan should be perfect
gto oil pan at $265, truck pan from the junk yard and f body pil pans i've used all had a perfect seal surface.
Beware!
In the old Chevy days, GM made the cheapest, always-leaking, stamped sheet metal oil pans and just about every aftermarket pan was better. Now its the opposite - GM makes quality cast aluminum, structurally strong pans with a gasket design that rarely leaks, while every aftermarket pan (so far) is inferior. Personally I would never consider the non-structural LS pans that Milodon and Morosso are selling.
Agreed, I would suggest avoiding the Holley LS oil pan.

It doesn't look like it would come close to fitting a 2nd gen.
I'm very active on the nastyz28 forum, and know that several people there have had success with the '98 - '02 Camaro LS1 F-Body pan.
The only pain involved was the instructions says the pan uses your existing factory oil filter. I had to do a lot of searching to finally get the correct filter. It uses the newer LS engine oil filters, not the ones from the from the late 90's early 2000's.
Hope this helps!
