with FACTORY horsepower

As long as they aren't worn out and seal...you'll be fine

The second you hit 401 on the dyno though, you'd better bring a towel because that seat's gonna get WET! It is accepted convention that 400 is the precise horsepower output breakpoint for leaky seals. The seals just won't tolerate any more horsepower than that. At 401 HP, the seals are compromised by the pressure differentials between the exterior and interior. The induction is seeing a steady state pressure drop while the cabin pressure remains relatively constant...

I think this is the first time I've actually literally laughed out loud at a thirdgen post.

What happens at 402?

OH!

don't get me started on 402!!!

Lets just say, you'd better have a full cage with nascar style doorbars and at least a good 5 point harness (maybe a 10 point, they're good all the way to 804 horsepower). But 402 isn't as much of an issue with t-tops because the heater core shuts down at 401.8 H.P (winsheild wipers get unstable too). so you're going to have to do something about that first. Then you can worry about what the T-tops do at 402.

Dont forget, at exactly 150mph, firebird headlights become unstable and can hyper-extend backwards or even snap off. Many a firebird driver has been injured or killed by headlights flying off and going through the windsheild.

Come one, I know someone else has wondered how fast you would have to go to make the headlights flip backwards. When the headlight motor went out on my friends firebird, we figured out that the headlight will come up on its own at about 80mph.

Lol, I actually rely on this fact to get my passenger side headlight to come up on the way home from work! It doesnt always come up on its own...

lol, oh my goodness, that's pretty funny...sorry man. Seriously, I'm 99.9% sure that these are unrelated. T-tops will only leak due to a a bad body and definetly i you have bad seals. If they don't leak right now, they will not leak with these mods.
