Interesting, Never heard of this version

Wonder what a 320HP R/T headed motor would be like bolting on a Speedmaster Air Gap copy with magnum head bolt provision AND bolting on 1.6 rocker arms?

Would it get 1 hp / 1 cid ?

I'm thinking it was probably 330 HP delivered but conservatively advertised at 320HP??
