Does a 70-71 CJ C6 with R servo have ANY stall built in?

I'm planning on a mild build on my 429CJ and maybe even go with a 460 crank if if needs bored at all... I am wondering if this tranny I have will provide 1800-2000 stall IF anything??? I am running a 3.70 posi in a 3800 pound 70 Torino Cobra with me weighing 200 pounds...Please feel free to offer your thoughts and opinions! Thanks, Troy

Don't know about the 429-460 c6 but the the 351c 4v headed engines with c6 had a I believe 1800 stall from the factory but they had a different bolt pattern it was a 10" convertor and would not fit the 429-460 flex plate without some machining.
