What stall speed do I need

[85chevy86]

From my past post some might remember I got a 350 off a friend. The cam he said is a Tpis and that I might need a bigger torque converter stall. Well when I called Tpis they said it does not sound like on off there cams. Here is everything I know

Intake- Rocker Ratio= 1.5
-Hot Lash =.009 IN

Exhaust- Rocker Ratio= 1.5
- Hot Lash =.009 In

Intake & Exhaust
Lobe center sep = 110.9 cam deg
Valve overlap = 11.5 Crank Deg

Intake
Valve opening =10.2 BTDC
Lobe Center = 106.9 ATDC
Valve Closure = 39.3 ABDC
Duration = 229.5 Crank Deg
Max Cam Lift = .35311 IN.
Net Valvelift = .52967 IN.
Lobe ‘Area’ = 27.73 IN * Deg

Exhust
Valve opening =56.3 BBDC
Lobe Center = 114.9 BTDC
Valve Closure = 1.3 ATDC
Duration = 237.6 Crank Deg
Max Cam Lift = .38154 IN.
Net Valvelift = .5723 IN.
Lobe ‘Area’ = 29.96 IN * Deg


According to Jegs chart it looks like 1500-1800 stall would work.
*Can someone let me know if that is right? Also what is the stall on a stock converter?
*what would you recommend the stall be?

The truck is a 1986 c-10 350 with 350 trans

Thanks
