The post on Dart blocks got me to thinking. I see gen 1,2, and 3 listed all the time on Moparts. Not being a Hemi guy exactly how many gen's are there and what are the differences.

1970 Duster
Edelbrock headed 408
5.984@112.52
422 Indy headed small block
5.982@112.56 mph
9.42@138.27

Livin and lovin life one day at a time
