i run hydrualic cams in my engines, and am getting ready to install a new 305h comp cam in my 468 bbc, i usually run up into 6000 or better rpm range in my jet boat, what i am wondering is what lifter i should be running in your opinion? summit has told me to run howards lifters, and jegs has told me to run comp pro magnums, any thoughts? i also heard that rhodes lifters were the best, ??????????
