Just the engine... it will depend on the year and if it is complete in running condition or needs rebuilt.

There is no Big block or small block in Pontiacs. They were the same size. "67 did have the 400 and 400 HO available for the Firebird.

There is no "small block" , "big block" with Pontiac engines. The physical size is the same from 326ci to the 455.
Everything should bolt right up.

You can start by starting a dialogue with the gentleman at www.78ta.com He has a good help section, has links to companies that sell literature on the subject, white papers on the Pontiac 400, and is open to direct questions.
Pontiac uses same block no small or big, Chevy describes their engines small or big
Yes, you will need the Pontiac motor mounts, and the transmission for the Pontiac has a different bolt pattern than the chevy, so a Buick, Olds, Pontiac turbo 350 or 400 will be required if it is an automatic. If a manual transmission is used you will need the Pontiac specific flywheel and bellhousing. Pontiac also has the starter, battery, and fuel pump mounted on the opposite side from Chevy, so you will need to address these issues.Overall it is not that hard of a swap, the parts from a similar year Firebird all fit the Camaro, making it pretty much a bolt in.
