Because the transmission is almost two inches longer than the th350, you'll need to move your engine forward that distance or move the t-case back and do work on your driveshafts. It seems the consensus here is it is best to move the engine forward.
That's how I did my 1972 K-10 'Burb. Different output shaft, moved the crossmember forward. I also changed the transmission linkage. I got the output shaft and linkage from Advanced Adapters. Had to get a TV kit from them too to mate the TV cable to my carberator.
