I can about guarantee you would need to change to a reduced-diameter air filter (or hammerhead, etc.). Just do also check the coil specs, as you may also need to wire in a starter button on a separate circuit. But the 302 (if that's what you have, or 289) vs. 351 dimension difference may help mitigate on both points. As you say, hopefully some other HEI Goose owners will comment.
