air filter
I have the Shelby aluminum 427 with a single Holly and have plenty of air with the K&N filter & K&N top filter. If I change it to the stock style Stellings the engine is severly air starved. I think it is the top K&N filter that makes the most difference. They are expensive but what do you want, performance or looks? When the hood is down you can not see either. Change them back when you take it to a show.
