If you don't put the engine back to factory position/angle
headers will hit the steering linkage, plus headers will drag the ground
I choose to split the torsion bar cross member in the middle,
section the sides , so i could widen and raise the TB crossmember
Then I bent 2 1" tubing to reinforce the sectioned area
was even able to use the original bolt holes to install the trans cross member
maybe these pics will help make sense.. lol
floor is raised 4"
this crossmember (68 "b" body) does set lower, but no lower than the oil and trans pan
I could have made a custom cross member,so, that it wasn't lower but just used what I had laying around (quicker)
eng is set at 3*down(toward rear end)
the other 2 u bend pieces are connected under the floor to cross members that serve as drive shaft safety loops and stiffen the frame connectors
