check and make sure the bellhousing has enough clearance for the flywheel to clear
i've seen in some cases where the bellhousing has to come with the engine, flywheel included and once you get the assembly out then pull the flywheel out through the transmission end of the bellhousing and then remove the bellhousing.

i know it seems bass ackwards but the mfg did not make clearances enough to allow the flywheel past that side of the bellhousing so you have to pull it all and remove it after you get the engine out.
