dropping SB oil pan in car

..ok speaking about my E body... the center link has to be removed...and I had to raise the engine just a little to get the clearance to REMOVE the oil pan..My eninge is a 340 also... so I think the work is the same..
Hope that helps..

BTW... when you remove the Oil pan.. install the timing cover before you put the oil pan back in... way easier !
