Fastest Naturally Aspirated Long Tube L98???
Whats the fastest naturally aspirated 5.7 L98 with long tube runners you've seen?
No FIRST intake, No over bored motors... Can they get in the 11's?

Whynot over bored? Boring the engine is not fluid to make that big of a difference.
What about cam, head etc...

Good question. I am interested in hearing the answer as well. I would believe quicker than low 12's and somewhere in the 11's. I think the stock bore size is going to kill this question though. Most people by now needed a rebuild if they are going fast.
