Whats the fastest you have been with FED product on board? Whether it be heads or an intake, let us know in the comments!

This one is
Chad Fegley’s 2010 Grand Sport Corvette

Powered by a brutally efficient 427 topped with FED F310 heads and an FED LowPro intake, this car delivers the airflow and stability needed for next-level drag-and-drive abuse. Boost comes courtesy of a set of Comp oil-less 88/90 turbos, force-feeding the BTR-spec’d solid roller combination with zero compromise.
Chad made history once being the first drag-and-drive Corvette in the 7s…
…He did it again as the first full-Corvette in the 6s.
