Intake design for stock appearing class and needed a winter project

I was lucky that day, but I’m a couple of tenths behind a pesky small block 67 chevy II. Any improvement and I can start to taylor the rest to the increase intake flow. Sooner or later a roller is in the cards. Also I can get 130 lbs out of the car with a couple of changes and going to 904. That should sharpen up my poking stick pretty well! Poke Poke Poke!
What class would you be in with a 4 speed?
