Re: cracking manifolds?

["White, Richard H." <White@courier3.aero.org>]

Yes, late model, single carb, cat.conv. manifolds are very prone to cracking. 
Now if all of them will crack is not known, but dont be surprised if it 
happens to you.  The Cat. Converter and manifold gets red hot, too hot 
really. Pop the hood one night and see for yourself. Many of these were 
replaced under warranty on earilier cat conv cars.  Richard White, 80 MGB
