It's all big dollars to go that fast with any sort of reliability. Really the heads are the main differences. If you buy a Brodix 5" BS block, I think they only cast one head for it from Brodix. PB5000 or something? AJ and others will cast (carve?) blocks for a variety of aftermarket heads.
That's what I thought.
