i just got my new c6 in from going from a 203 to 205 so i had to use the case with the longer shaft so i went ahead and got it built with better clutches and wide ratio planetary set and transgo shift set. the problem is after everything is hooked up all the way back to the transfer shifter i go to turn it over by the crank pulley to tighten the converter bolts and its all locked up.....what are some possiblities? we tried to bump it with the starter motor and still wont budge. the tranny and motor are mounted flush everything looks good i can see the drain bolt is where it shuold be in the flywheel. guess i shoulda checked it out before hookin everythng up and puttin the transfer in ..... any ideas?
