To move the oil filter does anyone make an adapter to just move it over a few inches? I can picture one, but can't remember if it's a real one, or only an imaginary one in my head? Would be pretty easy to make with a chunk of aluminum and a milling machine.
What's the concern with the driveline angle? With 137" wheel base you should have room to get that sorted out with most any reasonable engine placement?
