I bought a set of speed master bare castings when they first came out. Mine are LA style castings that look like an edelbrock clone. Think I payed $235 each lol. For that price I shoulda bought a pallet load. I have not messed with them since I got them. They are for a 408 build I have pushed off and pushed off, but now have the block done and ready for the bottom end. Looking at the ones in your link I am presuming that EQ isnt making these anymore?
