How many of you would buy an aftermarket block in low deck height. Aluminum, cast iron, up to 4.500 bore size.

Couple other points while I'm here. The RB is really unnecessarily tall for less than 572 CID IMO. One of many reasons I always liked the B eng. While I didnt weight it, the KB block is heavier than the INDY but it is stronger !no doubt! Indy was near production of better design block last i checked but it was RB height. The old Indy alloy RB used to be advertised at 144lbs FWIW. I think something similar to a KB low-deck would be a good seller considering the head options available for 4.8" BS
