|
As no surprise, matching the Mast heads up with a bigger 416ci short-block and 242/260-at-0.050 cam really woke them up, boosting output to 630 hp. With a big-block-like 370 cfm on tap, they can easily support 500 ci, proof once more that today’s cylinder heads can feed as many cubic inches as you can realistically throw at them.
