Can you use a 350 Chevy intake manifold on 283 Chevy?

No, a 350 Chevy intake manifold will generally not work on a 283 Chevy engine. While both are small-block Chevys, the bolt patterns on the intake manifold are different. The 350 has a larger bolt pattern. Trying to force a 350 intake onto a 283 would likely result in damage to the engine block. You need a 283-specific intake manifold.
