Will a 350 Chevy intake fit 327 motor?

Generally, no, a 350 Chevy intake manifold will not fit directly onto a 327 Chevy small-block engine. While they're both small-block Chevys, the bolt patterns on the intake face are different. There are some exceptions, however, depending on the specific intake manifold design. Some aftermarket manifolds are designed to fit both. You'd need to carefully check the specifications of the specific intake manifold to ensure compatibility.
