77 pontiac lemans/77 a body headers
Long time no post, but after some dispute. The olds 350 in my 77 lemans now has a 403. Now that I've got one problem, the flow tech headers I bought for it aren't working. I've tried almost everything massage with hammer moving the engine up with the crane, neither side will fit. Does anyone know of any good headers that will work on a 403 in a 77 lemans? Thanks for any insight!

Look for headers from a 2nd gen T/A with the 403. I'm not saying they'll fit but I know the 2nd gen F body Pontiac headers fit a Pontiac engine in a 73-77 A body.

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.
