well im 99% finished with my aod to 351 c converson and i ran in to a problem... when i mount the torq converter to the trans it spins fine and the fly wheel to the torq converter it spins as well, then i move to install the trans to engine it bolts up fine, ok so far so good now when put the fly wheel to the torq converter it spins fine but when i bolt it up all the way and mount it all to gether i cant spin anything its locked up. i have changed converters put a new pump for my trans in and nothing. the one thing i did find is if i put 2 washers on the torq converter studs that pushes the converter out a little then it spins fine..... so im at a loss what i was thinking was maybe if i get a flater flywheel... if they make one, if you ever seel the aod flywheel it cones out a bit i might need like a flat one, any one that has done this converson please help or if you know about trans misions. even the shop thats doing the work is stumped. so any and all info is welcome THANKS!!
