Sump / Oil pan height

[MurrayDonkin]

Hi all,

I have searched the forum to try find a definitive answer on the correct sump / oil pan for an LS3 install without success (apologies in advance if I missed something). I am trying to establish what is the maximum height the sump can be to ensure it clears the cross member and does not protude below the chassis. I have read that the Corvette C6 sump at 4.85" deep is correct one but also found some conflicting information so hope it is an easy one for someone to clear up.

Thanks
Murray

My friend has the Camaro sump on his Ls3

Thanks, good to know that one will fit for sure.

The flattest ones will be the big wing items from the c5 ls6 and the two part item just after that. Next will be the ls3 sumps. I'm not sure if you have side clearance for a big wing item. Those are also the best design internally.

Thanks for the reply. I was hoping to fit one without the "wings" but just wanted to be 100% sure of the right height to get.

GTO Sump off of a LS1 powered goat will also work. Had one on the self until about a year ago ,sold for scrap, which is all a wet sump system is worth on this car if you plan on doing anything more spirted than a Sunday drive on motorways. imo

Which sumps do you recommend? I've seen some dry sump kits on US Ebay that look reasonable.

I had an ARE system on my first GTR we were able to data log all engine parameters during several track days an never saw a single incident of low oil pressure. The new GTR is not done yet, we have a Daily system installed. The Dailey system is a very clean application. The pump is actually mounted to the pan which eliminates the need for several of the external hoses and a oil pump mount. The Dailey system is more expensive. Lee

My car had an LS2 when I got it. It had oil pressure issues on track.

My rebuild included an LS7 with dry sump. I would not build an Ultima without a dry sump.
