The principle reason turning apparent simplicity into real world complexity is the dynamic ‘stop – start’ nature of the flow through the engine and the fact that air is very much heavier than is often supposed. Rapidly changing rates of pressure and suction bring
Busted Valve Lash Myth
All too often the effect of valve lash on power output is considered very much a secondary factor and a small one at that. This may be so but the ramps open the valves relatively slowly and during that period the flow, into and out of the cylinder, is little more than a nuisance leak
Stroker Strategies for Higher Horsepower
Such strategies are already very popular with those building small block and big block Chevys as well as small block Fords. In the main, it is a cost effective way to deliver what most customers deem as power – that is more low speed torque. Generating extra cubes via a stroker crank is a good
