okay, so I have an 88 5.0 and I had it rebuilt at a local engine shop. They put in new crank bearings, pistons, rings, had it bored .030 over and it also had an F cam, and mildly ported explore intake and heads. I'm just wondering if the car will run on the stock tune and with being a speed density car. Also will the stock injectors be able to handle the load. The rest of my fuel system is also stock. thanks in advance for the help!
