about a year ago I sold a 55 "A" intake manifold to a fella that needed one for a stock Tbird, etc. Well, about 2 months ago, he notified me that the intake was cracked. I had it magnafluxed, not thinking that it had to be maganfluxed on the interior near the coolant openings...because I understood only later on that the exhaust was blowing white smoke.

1. Has anyone ever heard of any stock, cast iron, Y block intake cracking from the inside? (no cracks extending to any outer edges, and I cannot see anything on the interior - really don't want to pay again to have it magnafluxed)

2. Would a cracked intake such as the one described be able to have a magnafluxing?

I ended up giving the fella his money back...some people thought I was crazy. He had the thing about 9 months. Lord only knows what could have happened since I sold it to him. I had never run the intake myself and had received it in a swap deal with several parts...

Considering running this on my blown set up I am working on currently.
