1st time down the strip
sounds like a fun combo. The .630 reaction time can be ok or not so good depending on how the timing equipment is set up. I have raced at 2 different drag strips and the way they read the reaction time was different. At one track a perfect reaction time was .000 at the other track a Perfect reaction time was .500. If you went .499 you red lit. On my first time down the track with my car back in 1993. I was running a 1967 Dodge Dart GT with a 340 that was rebuilt stock except for an Erson cam and Small port closed chamber heads off of my 273. Mine was an automatic. I had a peg leg rear axle with street tires. I did a burn out to get the 1 tire sticky. then a hard dry hop to spin the other tire. Once both tires were sticky I just pushed my foot to the floor as har as I could. The car got lucky and launched hard and didnt spin a tire at all. The best time I had was the first time down the track. I went 13.78. I cut a .501 light with a .500 being a perfect light. It wasnt skill or anything...I was so nervous and excited that I launched to early and thought I red lit. I now launch my street cars always when the last yellow is still lit. Once you get the traction problem handled, you will find yourself heading for the 13s in no time. The power is there just need to hook up.
