450-500HP 360?

My 416” made 500 hp on a dyno with ported iron heads, a decent size solid flat tappet cam, Holley Strip Dominator intake, 850 carb and 1 5/8” step headers.

Strokers usually make more overall power because of the extra volume. Like said, put some heads on it that flow over 250 cfm to take advantage of that and you’ll get there.
