Chevy Big Block Crate 454 Engine - Import Killer, Part 2
|
AFR's Tony Mamo, the chief designer of the company's line of big-block Chevy heads, brought a few sets of AFR intake manifold gaskets with him.

As expected, the single-plane gained high-rpm power but sacrificed low-end grunt. View Related Article
