Bittersweet! Great....no more 40 year old heads but still a limited supply of 40 year old 340 blocks or 20 year old 360....both of which will need a lot of specialized machining to take full advantage of the power potential. 800 hp will make short life of even a decently prepped OE block....maybe now the Edelbrock invested time and R&D into producing the first LA head redesign in probably 15-20 years maybe Dart...or SOMEONE can get their act together and get us a nice USEABLE race block at an AFFORDABLE PRICE!
