Bull! I agree 100% with Dave. You want to change out your cam and lifters, not build a race engine, or plan to build one later. That fine article from the Crankshaft Coalition, (written with a lot of input from TechInspector1 who sometimes graces us with his input here and who knows more about cams and integrating them into any engine) provides excellent guidelines on choosing the right cam based on the engine you have. Don't let anyone belittle you about what you want to do or the amount you have budgeted. You don't need any master plan if all you want to do is swap a cam. You can use the information you have to get a modest HP increase, and also pick up a modest lope that will let everyone know you're not running a stock engine. Forget about horsepower goals, torque goals, and all the other high performance, high efficiency falderal. Dave very accurately pointed out that you're going to need to go into the engine and do some machine work to worry about such things, so pick out a cam that's not too wild for your compression ratio, have a ball, and ignore anyone who tells you you're wrong to buy a cam and lifters for an otherwise stock engine. Been done that way for many, many years, and you can always go bigger down the road, when you have the need, and maybe the extra bucks to play bigger. Have fun!!
