• Frankenstein M311 – The Monster Series is the first threshold into HP creation far beyond any OEM head. Frankenstein introduced another level of horsepower when The Monster was brought to life. FED poured our arsenal of precision engineering into a common cylinder head and woke the industry. Intake and exhaust chambers are 5-Axis CNC ported with our latest high-performance program, meticulously hand blended and deburred. Our strict quality control processes ensure extreme attention to detail and precise tolerances. High quality components include FED’s premier stainless steel sever duty valves, custom PAC .700″ lift valve springs, titanium retainers, bronze guedes and hi temp silicone exhaust o-ring gaskets.
• Johnson Link Bar Lifters – 100% American made, Johnson leads the way in quality and performance when it comes to lifters.
