| − | *High leak-down rate flat tappet hydraulic lifters such as Crane 99377-16 Hi Intensity Hydraulic Lifters because we are going to use "too much" cam for the SCR. These lifters will reduce duration by 6-10 degrees under 3000 rpm for better bottom end torque. | + | *High leak-down rate flat tappet hydraulic lifters such as Crane p/n 99377-16 Hi Intensity Hydraulic Lifters because we are going to use "too much" cam for the SCR.

*With pistons at 1.561", rods at 5.703" and crank radius at 1.740", the stack measures 9.004", so with a nominal 9.025" block deck height, you would need to make a cut of 0.021" to get to zero deck. A 0.040" compressed gasket would then put the squish at 0.040". | *With pistons at 1.561", rods at 5.703" and crank radius at 1.740", the stack measures 9.004", so with a nominal 9.025" block deck height, you would need to make a cut of 0.021" to get to zero deck.
