On the FE Forum, back on July 29, 2009, KC posted a special purchase on Genesis iron blocks. The cost of the upgrade to a Pond aluminum block at that time was $1,200.

If my memory serves, the Pond block saves about 125 lbs over a vintage FE. Just speculating, but the Genesis is probably heavier than a vintage FE. Having driven a Cobra with both an iron block (w/aluminum heads) and one with aluminum block, I definitely prefer the Cobra with an aluminum block.

767jockey was the individual here on CC who had problems with his Genesis block, though he purchased it directly from Genesis and not from a dealer such as Barry R or KC.
