1). Don't even think about racing a newer 98+ TA/Z28 with your 98GT if it's stock. They won't have any problems slamming you. My 02 M6 TA went 13.2 @ 108.7 stock w/ 2.25 60.
2). Stock intake is POS, mine blew just sitting at redlight. Didn't have rearend probs till I lowered the car, and that was the shop fault for not adjusting the snubber. Your heads suck for flow, replace them or get a better intake and S/C it. If you want to make power, talk to some of the guys on here like Hammer, and Mustang92. They've got some really nice times and know how to get where you need/want to be
