When it comes to camshafts there is never a shortage of opinions or available grinds. And one thing that I always find amusing is the “ideal conditions” world that so many hot rodders, racers, and tuners seem to think they are in, when in fact some very small percentage of them are in that place at all. If you are racing at very highly competitive, elite, or combination limited levels, where every single horsepower can make a difference between winning or losing, then having the perfect camshaft might be the difference over a weekend of racing. But if you aren’t in the small percentage of racers who find themselves in that position, then you open up a world that includes a lot of camshafts and engine components that will give you everything you need.
But do you have to have a different camshaft for your LS engine if you are running a carburetor instead of EFI? How about if you add boost to it? Richard Holdener has done the testing so that you can see the answers right here. Watch
DO YOU NEED A SPECIFIC CAM FOR BOOST? WHAT ABOUT FOR A CARB, FOR EFI OR FOR NITROUS OXIDE? WHAT IF I TOLD YOU THE SAME CAM WORKS ON ALL THOSE APPLICATIONS? HAS RICHARD LOTS HIS MARBLES? CHECK OUT THIS VIDEO WHERE I RAN THE SAME CAM ON A CARBURETED LS, A NITROUS LS, AN EFI LS AND A SUPERCHARGED EFI (GAS AND E85) LS. WHAT HAPPENED WHEN I RAN THE SAME COMP CAM DESIGNED FOR AN NA APPLICATION, ON ALL THESE DIFFERENT COMBOS? FULL DYNO RESULTS.
