I have this engine setup..

350 bored .030" over,
461 heads,
dual plane intake,
10:1 compression,
cam specs are .515"/.515"-300*/300* with a 108* lsa.Power band is 2500-6500

the truck weighs 2850lbs and has 3.73 rear gears.

what would be a good stall just for maily driving on the street and a little track time?

i was looking at this converter...

stall speed for that converter is 2300-2700
would this be a good chioce?

there is a guy i know that will sell me a 3000 stall converter for $50 if it would be better.
 
IM assuming your not running extra tall tires here, ID suggest a 2800rpm-3000rpm stall converter on a 700r4. or a th350 trans
I generally try to keep the cruising rpm at or below 2800rpm at 70 mph with the trans in its 1:1 gear, if you have an overdrive trans that drops it down into a comfortable rpm range when matching gears to tires, BE VERY SURE to get a LOCK-UP converter for OD and a EFFICIENT TRANS COOLER so your not building excessive trans fluid heat cruising on long trips, obviously having an overdrive top gear, and a lock-up converter will be a big plus on engine life

sorry,i forgot to say that it was a th350.
The tires are 26" tall.
Can i get away with the 2300-2700 converter?

probably that speed converter (2300-2700 ) will be fine, but you would be having a noticeably faster response from a slightly higher stall speed converter , slightly faster ,simply because you'll be in a fatter section of the torque curve, without the minimal time lag the lower speed converter will provide as it catches up to that part of the curve, on the plus side were only talking about a minimal advantage and the lower stall will produce less trans fluid heat to dissipate
