I want to mount an LQ4 1.5"-2" forward of the stock sbc position in my 85 k3500. Will the oil pan clear the engine crossmember with it being mounted that far forward or will I have to cut up/modify the crossmember?

I'm mounting it that far forward because I'm also swapping a 4l80e in and it is 1.5" longer than my current setup. I want to keep the trans crossmember in stock location and retain current driveshafts
