Specs: 233/242 .629″/.629″ 113+3 The Night Fury camshaft is a very potent grind for those looking for maximum peak power. It has been proven to lay down over 500 whp with proper bolt-ons, on stock cylinder heads. Due to the aggressive nature of the grind, stock cylinder head thickness must be maintained. If you mill your heads, it is imperative that you check piston-to-valve clearance. Automatic applications will also require an aftermarket stall converter.
