I've been running in S/G and I've been 7.4 bracket racing in a 235" S/C dragster. But those are easy to run. I feel a door car is more challenging. However,... I'm not one to push the envelope before I think I'm ready. Having said that, I feel comfortable in the 7's. The next step I would think, would be T/S. But I know I don't want to push the mid 6's to be competitive. I'm looking for a T/D now to get ready for 2015. The Vette I want to take me this year and so on.
