I know beaten to death 700r4 converter

[djfxall]

Ok I want to be realistic here I have a 71 chevelle 355 9.5 to 1 compression afr 195 street heads going to be changing the cam soon to a solid howards roller the smallest they make for sbc. Figuring hp around 425 450. I have 3.73 gears and 26 inch tires. Have a 2000 stall that came with the trans from mad dog transmission back when they were outlaw trans. I recently lost 2/4 band so I am gonna replace it so the trannywill be out so I am gonna add some goodies like a new reverse manual valve body with engine braking. What stall and what converter this is a daily driver build that is more protouring then drag. Tci says dont run a converter thats higher then your highway rpms. Patc says run a 3200 no problem its streetable talking about the mega raptor 1. Confused on this one also torque multiplication. So many variables here any help would be nice. Will be running lock up.
