That's where your fuel inlet will be.this may sound stupid, but why does it need to be cut out like that?
All your cables/lines pass through those holes, for trans, throttle, cruise. So no, they'll be in the way.wouldnt it be clear of it in the first picture I posted?
Ok you should be good then.i'll only have the throttle cable runnin there. this motor is for a conversion in an 06 F350. trans is using a PCS.
