Agree! I think flat tappet cams are great until the lobes or lifters get worn down and ruin the engine. I also think roller cams are great until a lifter fails and and the roller wheel/bearings go through the engine and destroy everything and break out the lifter bore. Just don't think there is an absolutely clear winner here. Some good luck and Karma must be involved. I am currently running a 251-259 Ultradyne SFT grind in my street car. I have 3500 miles on it now and 40+ dyno pulls on it. I have not had a valve cover off since it left the dyno about 3 years ago. Valvetrain sounds quiet, even and smooth. Doesn't mean it won't flatten a lobe the next time I drive it which will be tomorrow. But trending the right direction. Love the way a properly adjusted SFT cam sounds through a full exhaust system.
