i swapped my 305 for a 350 and couldnt use my old oil pan, the new pan is longer in the low part, well my exhaust is the factory style, one pipe from each side that turns into one.....well you know how the pipe goes inbetween the crossmember and the oil pan?? well my pan is too long for the pipe to fit into the littl gap.... any suggestions? how about going ahead and running true duals?
