It can't just be the aluminum block. The m52tu's are aluminum block engines and there have been no reports of the same thing happening that I've found.
If I'm right and they aren't affected. I still think a 328 makes a better track car. Hell I'm pushing the same kind of power as a stock 330 now and I feel much safer about the engine out on the track when I'm up hanging out at redline.
