A little ? if you were any slower on this you would be back in the womb ....

Yes you can use the 69 bellhousing on it , but you have to use an external balance 143 tooth flywheel and there wasn't one from the factory. But, lets not ASSuME it's stock. Do you know for a FACT that it is a factory stock never been monkeyed with engine ?
