Displacement only huh?

So we didn't use that in the past but we've got cars in most classes running competitively based on stock hp. How did that happen? ummmm, the process worked?

Now we are to switch to displacement only. If we switch to displacement based classification are we moving older cars to new classes? Or just using displacement to improperly class new cars against older cars?

Jeez.

Displacement only would cause problems.

TR8 = 240Z = 260Z = 300Z = ~175 rwhp +/- 3%

300z and TR8 have to go to R based on displacement.
