with the LS2 and the Mcloud bell set up you can see the protrusion of the bell that accomodates an optional starter mount if used. I am using a hydraulic TO. The header collector shown in the picture is a set of mid lenghts that don't have the right angle/clearance for the Mcloud bell. I would like to go with the Shoenfelds but just like everybody else, I just want to avoid shipping headers back and forth like I'll have to with the ones I have now. Was told these would work 100%.......uh huh.....
