I would like to ask a little bit more power from this 400 and I知 wondering if someone has a suggestion as to what size and style camshaft I should put into it I知 Looking for better performance and just a little bit more horsepower. I was also going to go ahead with Paul freeze ram air but he stopped making those castings he suggested I install some headers which will be tricky being that this is a first GEN convertible Firebird I found some from dougs that look pretty good and they should probably work any suggestions on that and would be helpful also
