Compacted graphite blocks are EXTREMELY heavy. The heaviest block I ever have picked up was the spare 99 Hemi block we had. It was a very short deck block with one side of the skirt milled away. No one likes machining them as they are hard on equipment too. FWIW my 99 Hemi ready to race, carbs to pan weighed in at 885lbs! For comparison my aluminum B1 is 525lbs
in doing a little reading on the blocks, it was stated the blocks can be lightened a fair bit and still have a lot of strength. It also stated that the correct tooling is readily available but since milling speeds require half the rpm and half the feed speed the machining costs are probably 3 times then grey iron. OK Al.....you talked me out of it.
