IM getting ready to fire up my forged 346 and when i was rotating the crank over by hand to get some oil up in it i heard a noise..every time i would let tension off of the breaker bar there would be a clanking sound near the rear of the engine or in the bellhousing. i know everything in there is tight, i tripple checked it. could it be the internals on the torque converter slaping around b/c its new and not all the way full of fluid? help me this is bugging me bad. thanks

 

ttt.......anyone i need to know
