Thinking about an LS3....

[mikidymac]

I am not sure about the iron block LS's but I have been told from many different sources and a good friend that is actually an engine builder for a living that at least on the aluminum LS's the oil pan is a structural member and to never use the stamped steel pans on them. I am no expert on the issue but I would look into it before you buy one. I know for limited clearance on the early chevelles the MAST Motorsports pan gets good reviews.
