The first thing I noticed and don’t like is the .300 lift number. I have a hard fast rule saying if I don’t have 200cfm@.300 lift it’s not going on my engine. That’s with any aftermarket small block head. I care about that number more than my do .700 lift because I can build from there. A nice valve job would probably help.

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
