1974 cast date - emissions?

* When properly rebuilt they will make as much power and torque as you can get from any FE.

* There is usually enough room on the block so that after the rebuild there is still enough room for a "freshen up" (I bored mine .025 over).

* They seem to be a little less prone to the overheating problems that some sideoilers suffer.

* 1974 blocks seem to get through the emissions just as easily as earlier blocks.

Thanks Patrick for your thoughts, really just what I needed to hear. When I first started to go in the direction of the 428 I know it was you and Rick Lake (as well as some others) that helped me to understand this was the right direction to go for a street car and not to 'overbuild' the engine. Of course Peter at ERA was also a big help in talking with Joe so that I received the right engine for what I wanted.
