This one was interesting. Didn't know that the 426 wedge was a dog off the line. I had the 'Runner taking the win at the top end mostly due to better breathing.

Yes,

The 426-S 'Street-Wedge' was a 'slug' coming off-the-line.

To get more 'oomph',

Back-in-the-Day, we would pull the Intake Manifold off and stuff rags in the Cylinder Head Intake Ports
and gasket-match the ports.

Then we would pop on a 1967 440 HP Intake Manifold with a 1" tall Carburetor spacer.

Then add a Carter AFB {750 CFM} with 1 11/16" x 1 11/16" throttle bores.

What a difference..............
