I'm looking at 98z with no internal mods but has a few bolt on.Such as mas air flow, 90mm tb, 3" exhaust and 175 wet shot . I was told it has run 11.63 in the quarter does this seem possible with stock 2.73 gears and convertor. I've been a bracket racer for a while and it just seems like you would need more gear than that if not a convertor also. Any help would be appreciated.
