I've got the LS2 Corvette sump on mine. Well worth the investment. Heaps of ground clearance. In fact It'll let me shave about 10mm off the bottom of the bell housing too next time I pull the gear box.
You don't just gain the clearance with this sump. You also get a labrynth of baffles in there for
oil control and the pickup is pretty much central with all the baffles pushing
oil towards it.
I'll snap a pic of it on the weekend. The car is on the hoist at the momnent.
Ive seen plenty of pics of welded LS sumps over on LS1Tech.com
Cheers
