Right - MOST Chevy intakes will set your carb level with the engine down 3 to 3.5 degrees at the rear.

In doing some more research it looks like you are all correct calling for 3" down on transmission - at 5" ride height measured at the frame by the rear cab mount- I thought I had read somewhere that the pumpkin in the rear should be on a matching angle - should that be pointing 3" down as well... (I thought it was 3" up - but then my drive shaft won't pass through the trailing arms cross member - so I can't be right there) I am extremely outside my comfort zone here.... so much so that I just read article after article on pinion angle that I've stopped making any progress on my build. Any help greatly appreciated.
