Highest flowing sbm heads?

You tell me what it takes to move 4400 lbs (with driver) with wheel spin - easing it out of the hole and terrible 60 ft times and still run a 12 flat box stock from the factory? It's not up to me to spell it out for ya, your much smarter than that (I assume). Would 112 mph be enough? Or do you want 115 ?? LOL.


So quick math for ya. At 4200 pounds and 115 MPH that’s about 500 honest HP. That’s a damn far cry from 600. You’d know that had you done it before.
