Behind the oil galley plug, near the distributor, there will be a four diget date code. A letter and three numbers. The Y4 was a 455 in '72,'74, &'76. It was a 400 in '73 &'77. Post that date code and someone will tell you what year of car it was built for.

It's a 1977 engine,probably out of a Bonneville.
The 7 in the 27 is the year. The P is the factory. You could send this number to PHS and find out what the car was.  johnta1 Pontiac Power RULES !!! www.wallaceracing.com

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
