A while back there was a discussion of aftermarket BBC blocks. I'm curious to know if anyone has first hand experience with either the GM Performance Parts BowTie BBC or the BowTie Sportsman BBC blocks. Potentially being in the market for a 4.5" bore block, I thought I'd see what people thought about this option.
For my use I'd be leaning towards the BowTie rather than the Sportsman since the BowTie accepts Mk IV cranks, oil pans and timing covers. Sportsman is a little cheaper but that difference would be more than eaten up with the cost of a new oil pan.
Anyone else have any thoughts or experiences?
