What are the best mods you can do to speed density without coverting over to mass air flow??? I want to keep my speed density so I can keep it simple when I redo my 351w engine with some mild mods like the compu cam upgrade.....

You can do just about anything to it: Heads, intakes, headers, exhaust, CIA, but your cam choices will be limited. An adjustable fuel pressure regulator will help if you plan to keep the stock injectors in place. A mass air kit will work well with any cam, but even it needs a little tuning to tie everything together and get the most out of your combo.
