Double Plane Intake
The engine lugs in 3rd under 35-40 mph cause I got stupid high gears 2.96 in it for the engine . But as you can see even with low cr large ish cam and single planes makes good low end torque.
But since the OP running a 402 version his would work even better.
P.S. just cause they don't dyno under 3000 rpm doesn't mean it's a stone under there. It's cause their not concerned with under 3000 rpm performance in a wide open throttle run like a drag race ain't gonna see down there. Plus driving is a part throttle activity don't know how well a WOT dyno run is gonna tell ya what's going on under 3000 rpm.
