Ls7 exhaust manifold help I am building a 55 studebaker pickup with an lq4. I am interested in using ls7 exhaust manifolds due to my narrow frame rails and limited clearance. Lt headers are not an option for this build. I am getting close to mocking up the motor in the chassis and it would be helpful to see some measurements of these manifolds on a motor so I can decide if the will fit between my rails. I know they have a funky flange but I am prepared to deal with that. Thanks for the help.
I don't have any specs but I can tell you they are very good from a performance standpoint. I put a set on my 2005 Vette (along with matching cats and midpipes) and it picked up 3 tenths in the 1/8th mile. They are a center dump and don't flare out at the outlet so I am guessing they should fit your chassis as long as your motor mounts dont get in the way.

rough measurements:
from the bottom of the mounting flange to the collector - 7"
Then, using the mounting flange as a reference plane (i.e laying it flat on a table) distance from
plane to inside collector flange 1/2"
plane to outside collector flange 5 1/2"
