lunati street master cam

Ive run that cam and many others,the 108 will give you a lopey idle but it will also incease low end torque and create explosive power above 2,000.A basic guideline is the tighter ls gives you a lower rpm range and more torque where a wider ls gives you a broader range and a bit more h.p. but a loss of torque/lower end.Alot of people think that a mellower idle and more vaccum/throttle response is directly related to your low/mid range torque but the dyno and the dragstrip told me a different story.you will accelerate faster and have more torque with a tighter ls and the proper convertor/gears.With all that said modern cams with agressive lobe profiles have thrown a curve ball in the works by offering cams with a 110 ls that have a ton of lower end and good vaccum for the duration but also not sacraficing top end.You will notice cam durations that used to reccomend 10.1 compression or better now reccomend 9.1 or so in the comp xe series due to the efficiency of the design,they are really about the best dual purpose street strip type cams out there I have ever used.
