I'm looking for full length headers that will work with my 1991 F-250 4x4 w/ a 351W and C-6 trans.
The problem is that I need at least 1 5/8" primaries....so I think the Lightning route is the way to go. I don't think the axle or the suspension will cause interference....It has 8" lift with leaf springs and a 3" body lift which will set the firewall a bit higher.
Does anyone foresee any problems with the compatibility?
