Thanks for all the info everyone. I know that there is no right answer to who is the best, but all the replies will help us narrow it down. I know that the shelby block isn't exactly original, and we aren't exactly set on using that, it was just an idea at this point. In our research we have found one builder who uses original 427 so blocks and sets them up identical to the originals. We are still scratching our heads as to wether or not to use an aluminum, original, new block, ..... I guess when it comes down to it we are looking for the original look with around about 500 to 600 horse, and wondered if there was an aluminum block that looked and functioned similar to original, or if the iron block is the way to go. Not looking for a fight from anyone, just want to know what my options are, figuring that everyones experience combined should give me some great ideas. Thanks
