Early DRE Detroit Racing Engineering 2x2 Cadillac intake manifold. Early version that does not have the stress relief cuts in between the runners. These would crack so they started cutting them. This one cracked and relieved itself. Cracks are superficial and cracked closed to where the cut would have been. Intake isn’t warped and function isn’t effected. You could repair it or leave it the way it is. Produced in the mid 50’s and is a very rare piece. Has 1949/50 Carter WCD’s and all the correct linkage.
