Not sure what my 727 was originally out of, but I put 3 small bends in the upper part of the dip stick tube to clear the TTi headers. The bends were made towards the firewall and it fits fine in the car.
Add a set of raised port heads that only have about 1/2" between the back of the head and the firewall, to go w/ 2" headers in a 68 fastback, and you`ll be hunting the right flexable set up! (1967 440/505 r/b and 727)
