Summit small block cams

Whatever this is worth, I put the 6900 cam and lifters in my 318 last year and have driven about 3000 miles with no issues. Used the supplied break-in lube, high zinc oil, and left the stock springs for break-in. I'm ashamed to say, the engine was cranked way too long before firing and running and the cam still seemed to survive. Pulls 19" at idle.
