You can't swap between classes, the argument for this rule was that people were running GT with legal SS combos to avoid a potentially losing heads up runs.

So I have a 89 roller 302 in the garage. If I run that block with a set of 68 302 heads I could run it in GT because it would be a hybrid? And I could claim it as the merc 68 302/220 combo with the 4150?
