Default Aluminum block LT4???

I don't think I'm crazy but....is it possible for a late 1996 LT4 to have an aluminum block??? Far from being an expert, I've had several look at it including my mechanic. Looks like, acts like, could it be aluminum????

It certainly wasn't offered from the factory and I've never heard of a LT1/4 aftermarket aluminum block. Cylinder heads yes-block no.

GM offers a number of aluminum blocks over the counter. They are not cheap. Check Scoggin-Dickey's website http://www.sdpc2000.com/cart.asp?act...tart&catid=734

LT4 didn't come from the factor with an aluminum block...

Like they said, aluminum heads, not block. I don't think there are any aluminum LT1/4/99 blocks anywhere. The lack of standard distributor mounting and the reverse flow cooling means that the standard aluminum blocks won't work. Maybe with some machining it can work, but I doubt it.
