I bought a stage 2 4.1 that I been piecing together for a while now. Finally poured oil in it to prime the pump (which I've had zero success at). I noticed there's no revision on either side of the block for a dipstick tube. My car with a 109 factory engine has been off to paint for too long so I have nothing but the internet to reference to. Would the stage 2's have had a pan revision? My pan looks homemade and all it has is a drain plug on bottom and a bung for the oil pump suction line on the right side. Any help would be appreciated
