I wouldn't try and get that motor down so deep in the crossmember. There are many people who raise a sbc because it looks so deep in the bay....... when they put a gen I sbc in the stock camaro clip local. I would imagine there is plenty of vertical real estate for you to raise that LS1 aswell. probably save you a lot of headaches and maybe look better from the topside when you are done to?
My son has an LS1 and they have oil leak issues something to do with the pan. Apparently a labor some fix to? If you do change the pan maybe look up the pan leak issue fix at the same time?
Gonna be killer. I like the stance and the front wheels location looks perfect.
