This is a cast iron 4 bl intake for the 1968-69 400-455 engine . It needs to be media blasted , has the patina and surface rust , no cracks or welding . The books i read say it will fit the 1968 W-30 or W-45 .Casting numbers 398662 and the letter J on the front . Asking $125 plus shipping from zip 60034 , or you can pick it up . thanks BOB

 

Not only will it fit, it's even correct for those cars. The 68-69 W-30, 68 H/O, and 69 W-32 used this manifold, as did every other BBO car built in 68-69. Only the 69 H/O used a unique intake.
