Intake Manifold Paint blistering
Just finished rebuilding a 66 tri power unit and installed it on my 67 400 the other day. It was a beautiful Pontiac blue inatke manifold and then one drive around the neighborhood turned the exhaust crossover painted areas brown and paint blistering...man you talk about being pissed!!
No one wants to pop the hood on a sweet tri power setup and see brown blistered paint.
What do I have to do to prevent this from happening short of blocking off the crossover passages?
