I don't think the question of what is better but what setup have your seen at the NHRA/NDRA circuit! The guys that are out there draggin their car every week and on the road. Not just a track event or car show meet! You will see almost of those companies that KJ has listed have done well. Keep in mind, your combination of parts is the key to having a reilable killer setup. Just don't go cheap on parts and tuning!
