Has anyone used one of these new ZL1 blocks? I was thinking of building a motor with one as a base but was wondering how happy people where with them. Are they good quality for the money? I know that I could probably cover the cost of most of a crate 502 for the price of a new ZL1 block but that all aluminum block heads and intake would look sweet when you open the hood not to mention the weight difference. I thought that I had heard at SCR8 that COPO PETE's white copo has one of these in it and that thing fly's. If anyone has any information on these or knows anyone that has worked with them I'd appreciate hearing about them. Thanks in advance.
