Royce is right on.... |

I have had a lot of blocks and so has Royce and a 70 pound claim is ludicrous. It would be impossible to have an almost 50% increase in the weight of a bare casting no matter what style it is. The range in weights for FE blocks is less than 20 pounds based on the dozens if not hundreds I have shipped over the years. The later 427 is a little heavier but it has some extra material for side passges as well as the other features Royce mentioned. Walt, the G blocks are likely the C8 blocks that were made with extra phosphorus. The nodular iron rear case was made starting in 62 but during production in the fall of 68 Ford realized that they needed an identifier for the housings to preclude assembly error. Nodular iron is a type of iron where the graphite forms round nodules covered by an iron carbide shell. This type of iron is made through controlled use of magnesium to desulferize the iron and causes the graphite to form the nodules rather than flakes. Hawkrod |
