Where is the weak point

I have a 65 Barracuda in the build stage. SS springs, 8.75 with a spool and 35 sline axles. I have a 65 B body A833 4 spd. with a trunnion to U joint adapter, scatter shield, hyd. clutch fork ram, Mcleod flywheel and clutch assy., behind a potent 360. Where is the weak point in your opinion.
