You could do that. But, S/S production classes allow OE part numbered race heads, aluminum rods, titanium valves etc. They are closer to a comp engine than a NHRA S/S. No runner volume. Pistons are wide open. I'm not sure if they still have 2-4bbl classes. I know they have a single 4bbl and 2bbl classes.
