I'm in the process of a hemi swapped into a 71 dart,moved the master cylinder inside,i have no inner fenders and shock towers are moved as I'm using coil overs and have a aftermarket frontend,i brought hooker headers 5481,but on mock up with the hooker headers on the engine,#1 tube on the left side runs right with the block,so I'm having a problem with that,as it wont let me use external oil lines to the pan,not unless I reroute the tube,really don't want to go with a deep pan,also with the hookers after measuring they will set real low,i would go with tti,but will ask them if you can do external oil lines
