i have full faith in that tranny i have a hardened input shaft billet steel clutch hub billet drum raybestos frictions and steels billet servo piston kevlar band full manual valve body, and i will be sporting a denny's driveshaft with 1350 solid u-joints, and you know what, if i pop that tranny it would be the case, the case is the only thing im worried about, if it lets go i wll be getting a JW racing tranny case and build it from there. Im not too worried about it, thats the main reason i didnt do a trans brake. i am running solid mounts all the way around and i will be chaining the left side of the motor to the frame so i dont have too much movement. i dont anticipate a problem but you never know i expect to see over 700 hp at the wheels so who knows.
