Howards Cams Boost Retrofit Hydraulic Roller Camshafts
Howards Cams Boost retrofit hydraulic roller camshafts are ideal for replacing your flat-tappet camshaft. They're available with various lifts and durations, and can provide different idles including good, fair, rough, and lopey. They're ideal for competition and high performance builds featuring forced induction, but not intended for use with stock (OE) valve springs (thrust button may be required). Firing order, degrees of lobe separation, and intake centerline designs vary by application. Add over 70 years of race winning performance to your naturally aspirated build with the Howards Cams Boost retrofit hydraulic roller camshaft designed for your engine.
