Feel like my 440 should be faster

It’s January…….plenty of time for tweaks before car season gets underway.

Pull the heads, have them milled to 80cc and the bowls blended.

Get a 9.5” converter.

If that’s still not enough, put some gears in it.
I would go gears before anything, biggest difference you will feel with any modification. Definitely needs the heads played with as be a slug with stock ports
