Engine paint on exhaust manifolds
On exhaust manifolds on BB engines were they still painting them orange with the block? I have seen some BB cars, with some orange on them from 1970 MY. any cars have that in 1971? Also did it depend on the manifolds that came on the BB engines whether or not they got painted? Does anyone have a definite serial number range when they stopped altogether on painting the exhaust manifolds on the 70-72 cars
