I don't think it matters much what the head does at 300 on a race head. The early numbers go right out the exhaust port




Keep in mind everyone doesn't run an .800 lift cam in their small block or shift at 8000 plus RPM.

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
