removing seized engine from transmisison
I'm about to pull the seized engine from my 72 project. With the engine seized how to I rotate the flywheel so I can remove the transmission?

First of all a couple of questions. What kind of engine and transmission? What has the motor seized up? The last one I blew up presented a similar problem. Had to cut the oil pan off, cut some connecting rods, and remove some bearing caps. If it is an automatic, you will need some rotation to reach the torque converter bolts. Never blew one with a stick shift so other members will need to join in for removal details. A good reciprocating saw is your best friend at a time like this. If the motor is junk, it really doesn't matter.

but the torque converter will stay attached to the flex plate, however, the trans will come away when you remove the trans to engine bolts. As for removing the torque converter from the engine, you will have an easier time with the engine on an engine stand, providing it will bolt to one with the TC still connected.Regards from Down Under

A local friend does motor swaps for a living ... several a week. He runs into that "seized motor" problem too often. Granted, he is not doing vettes; most of his jobs are relatively late model front drive cars. He must not waste time because he contracts the jobs for local junkyards and an agreed fee he charges yards. Arbitrarily dropping a transaxle just doesn't happen. He has & uses a post lift for all swaps. He does charge yard more if motor is seized. If truly completely seized, he usually pulls oil pan off and pries on whatever it takes to rotate flywheel/flexplate. Bear in mind he is replacing motor & not too concerned if seized piece suffers further damage.

I got it all out and unbolted the transmission then slid it back a couple inches. Then I had enough room to take all three bolts out of the flywheel and the torque converter just slide away. It really was less difficult than trying to get thos bolts in the opening at the bottom.
