I put my master cylinder on the firewall becasue of a 350 conversion and run
the rear brake line the same as stock, down along the frame rail on the
drivers side. My exhaust also runs along the drivers side ( the same route
as the stock exhaust) because of the gas tank on the passenger side of the
frame. I have not had any problems. My front lines run from a
proportioning valve under the master cyl. along the back of the front cross
member the same as the stock set up.
