Another Mopar Off My Bucket List - Barracuda Fastback

Studying, studying, studying... It seems as though I'm constantly online looking for information for things. I've been worried about the availability of aftermarket aluminum blocks. I've read a lot of threads where people have said they're becoming hard to get and that some of the manufacturers have stopped producing them. Some say that there is a very long wait period to get one from Keith Black. Some have voiced major concerns about the quality of the ones from Indy. - And reports of defective workmanship combined with rude salesmen and almost no support from Indy makes me hesitant to order from them. I need to start making phone calls to find out what's true.
