Cams for 318's

They need rebuildable cores and they are not in stock at all times. Same with Rock Auto. They have nice reman's available when they are available. Catch my drift?

George Jets bought a set. Info in this thread: 302 heads and cracking
I'm sure that I don't understand the manufacturing process, but why didn't Chrysler address this problem with the cylinder heads cracking with the 302 and the magnum cylinder heads,? The same thing with their transmission's burning up because of the cheap transmission cooler they were using for a few years, these are the things that gave dodge truck's a bad name
