Yes Vinny the 305 engine itself minus the blower will make about 325 BHP. 15+/- PSI is going to fix that up thou.
The low low 7:1cr allows a lot of boost on pump gas. Simple low cost hot rod mods and upgrades allow the 305 to make good use of the supercharger. This 305 will not have a 305 cylinder head on it. But they are a OEM chevy head. Boring stuff.
you cutting the top of the bore to unshroud the valves with heads with bigger valves, or just letting them smash into the cyl wall/deck
