tatoy,
i picked a 408 for a friend at lme. im pretty sure i saw your motor, brian said it was going to PA.. it looked insane with that rocker set up, and that massive oil line.

Ya, I just found a spot for everything and got it all mounted up and the lines all cut and tight. I put the oil filter under the d/s front bumper right where the vacume pump was. There is an access door there that comes down with two 10mm screws and then just routed the line as needed.. Ya I think everyone seen my motor out there but me for the longest time..
