Hey well new truck owner here and new to the sight. I have always liked cars and racing. My last car was a Gtp. Im sure most of you know what that is but for those who dont, is a Supercharged Grand Prix that stock wasnt all that but 240 isnt bad. After an exhaust and intake it was a 14.3 sec car. So for a v6 that pretty good. Now i have an 04 sierra that will become better than a 14 sec truck. And thats about it. So if any of you guys know where i sould start with a 4.8 let me know thanks
