<VV> Manifold heat soak

[Gary & Susan Lowell]

Pontiac in 1963 on the 50 special super duty versions of their  
Catalina had aluminum exhaust manifolds.
A friend of mine had one of these that he bought from Packer Pontiac  
after the 63 Drag racing season. Drove it on the street for 2 years  
before he bought a Corvette.
He never had a problem with the exhaust manafolds - just gas pump  
jockeys wanting to "clean" the Plexiglas windows or leaning on the  
aluminum fenders. It was the fastest accelerating car I have ever  
been in. Faster than another friends 67 - 427 Corvette
