[HR][/HR]We have an LS3 6.2 V8 installed in our plane. In stock form, at cruise altitude between 9,000 and 11,000 feet, using 3600 rpm (1890 prop) for power, we will get 180hp. With the Hot Cam our horsepower goes up to 217, or a 20% increase. This is figuring a 3% power loss per thousand feet, and a standard day. Would the resulting increase in IAS, and the extra climb performance make the new cam worthwhile? The kit is $500. And, the cam in question is a bone stock GM LS3 component. Hoping that some of you "engine gurus" will have some good input!
