School me on Stock Eliminator?

I'll run ss/k, minimum wt of 2760 plus mandotory 170 lbs for driver =2930. It's a 235hp combo w 4 spd. The index is 11.30, with the hp were making it should run mid to hi 10.s. I think the 235hp was available in 64-67. In stock elim. this would run in j/s or j/sa, the a being for automatic. J/sa index is 12.75. in stock, nhra has defactored the hp from 235 to 220 wich helps it be more competative in its class by making it lighter or moving it back a class. Keeps racers happy, if thats ever possible!? The 273 commando is the 235hp,there are some guys running the 2 brl version also, to slow for me.
