I have an 88 GTA with a 305 TPI currently in it, bone stock except for the hyper tech prom chip, granatelli MAF sensor and hooker shorty headers. Engine has developed a lower end knock. Debating on what I want to do with the it whether I want to rebuild it bone stock, put a cam in it, or make it into a 355. Id like to keep true to itself by keeping it TPI. What id like to know is all that I would need to do if I decide to go the 355 route, what are the things I will need to change, fuel injectors, prom chip, etc. I'm not all about HP id like to make the car better than it is of course but not go overboard with it. My budget is kind of tight I have all winter to save up since the car is in storage for the next 4 months. Any advice would be much appreciated thanks.

Of course you want an answer specific to you, but this has been covered to death in older threads, and no one wants to type anything more than a dozen times.
Do some reading, take notes, briefly present what you think the correct answers are, then we can tell you either yes or no.
