Buying these four cams locally. We're around $1,000 so I took a gamble on these and I'm very impressed. So far the engine runs very smooth. I have over 10,000 mi on them at this time I guess we'll see how long they last. I do courier work. I put about 170,000 plus miles on my car every year so it won't take long to see if these last a while
I have 27,000 mi on these cams now and running as good as the day I installed them
