IHRA uses the NHRA factors and specs for the most part, in some cases there may be a hp difference, and IHRA usually publishes it on their website. The 68 Dart or 68 Barracuda fastback can run I, J, or K.
Minimum weights with driver -
SS/I = 2980 lbs.
SS/J = 3261 lbs.
SS/K = 3542 lbs.
NHRA has all the 68-71 340 combos' cylinder head intake port volume info wrong at this point, they seem to think that the 68-71 heads with 2.020" intake valves should hold the same port volume as the 73 340 and the 74-up 360 heads with 1.880" valves?
