If you want a tunnel ram...Put one on it....On smaller stock engines I use a Weiand tunnel ram and Holley 390 cfm 4 barrels

we used this on a late 70's 265 bone stock and knocked down 18mpg and it had great throttle response ( this went into a 76 chevy monza) Also screened intake gaskets helped....You can also mod a divider into the tract to make a single plane tunnelram but that involves more tunning...

On 327's I still use the Offenhouser "crossram" manifold these pieces work extremely well....all depends on the look you want...
