Don't even think about anything under a 5200 stall. Matts 360 picked up .50 in ET going from a 4000 to a 5200 and my 408 stalls at 5200 and is begging for more. And we only shift at 6400rpm

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
