Remember it is not just the engine you will be trying to put into the elevens, it's the whole car. If elevens are your goal you must look at the whole picture. Before even considering a cam the car must be weighed. Lots of people on the internet seem give opinions on cams without considering weight, suspension mods, gearing (rear & trans), clutch or torque convertor, and tire size & compound. A well planned car can make a hero out of a pump gas street driver without having to have gobs of horsepower. That is the reason some 455s with a xe274 run elevens and others run high thirteens. Another very important consideration is the altitude above sea level of the dragstrip you will be racing at. Big difference between sea level tracks and those at 2000 ft. With a four speed car espescially you will find more e.t. gains with rear suspension upgrades than a cam change. For early birds, calvert racing split mono springs, caltracs, and dual adjustable shocks are the only way to go. That being said, get a custom ground hyd. roller, you will be much happier.
