Anyone who says "no more than 2800" for a street car is probably just a couple decades behind the times or buys cheap crap.
I know a guy who has a hand-me-down Vig that stalls higher than that in his daily driver pickup he uses to tow his Impala.

Modern high stall converters can drive very well at low speeds and still stall high when you put your foot down, plus there is LOCKUP that makes the stall disappear completely at cruise.

 

what's the difference between a 9.5 stall and the 12inch and witch one
is better for a daily driver / fast street car ????

 

i just died a head and cam swap on my car, and to be honest i love it, i'll probably get bored of it later and want more like a super charger but for that i'm waiting no me to need a bottom end rebuild. Honestly stick with lt1 parts i got my parts ported from lloyd le2 setup and it cost me abotut 2 grand which isn't to bad conisdering you get the nice patriot gold springs with the package will should be the only springs youll need for a supercharger or cam setup.
