These purpose-built heads granted the power that ultimately broke drag racing’s 300 mph barrier and designed the first four-second Funny Car elapsed time. In recent years, Dart spread-port Big Chief heads have set the measure in classes ranging from Pro Street to Pro Mod. The launch of the inexpensive Iron Eagle and the PRO 1 cylinder heads for large and small Chevy V8s, backed by aluminum- and cast-iron engine parts, is also continuing this tradition of innovation. Dart considering expanded its product line to include small-block Ford and Honda parts.
