Just dropped in a TH350 trans and Chevy 305 engine and i can get the trans to block bolts in on one side but then there's 1/2" gap on the other. I took all the bolts back out and it seems like the torque convertor isn't all the way in the trans as its still pressed up against the flywheel even with all the mounting bolts out and 1/2" of space between trans and engine(engine and trans supported by separate jacks). I can see the "shaft" on the torque convertor where it goes into the trans...is it possible it's not all the way in?
