considered sealed.

*Does this make it legal or illegal to have the bottom lid on the LS cut open?
If opening the bottom of an LS lid is illegal, then the stock TPI airbox also illegal since it sources its air from infront of the radiator assuming you have the radiator 'sealed'. I don't see how it could be ram air considering the radiator itself is a huge bleed off of any built up air pressure.

*So the Fords still get the best rearend with more posi and gear options since I can't install a 9". And I can't install a bolt in 8.8 that I can order online for my F body? Glad I picked up a good T2R.
The strikethroughs don't paste into the forum. I thought Bryan was off his rocker (well, still do), until I clicked the rules link. I thought this rule has been in place for a long time, and it's now getting removed? 10-bolt or bust (or an Austrailian 9-bolt I suppose)?
