First, welcome to Hotrodders. Thinks aren't always like you see it here today.
Pontiac engine ID/info? No problem. Take a minute to see what's here
. The rest of the page is there if you want to take a look.
Pontiac info and sites
will give you some places for parts/info besides here- but there are guys here that can answer most anything Pontiac-related.
