Looking into building a new open small block. I seen these Tennessee Thunder Stick cams. Does anyone know anything about these or have had one that can tell me how they performed? Thanks!
^^^ mine i relieved the spring pockets . With stock valves. . everything is real real close . Its un ran . Now im concered i am going to pop a valve head off . Soo the longer , better valves are probably next .
Not to revive your old thread but did you find the issue?Okay so I’ve ran this motor 3 different races after building it. First race popped the valve retainer on the exhaust side. Fixed that. Second race went fine fine with no problems. Third race this past weekend made about 5 laps and broke again. This time it broke my rocker arm on the exhaust side and bent the push rod on the intake side??? After I replaced the retainer after the first race, I spun the engine by hand and it rotated fine. Didn’t feel like anything was binding up. But looking at what’s happening something has to be binding up in there for it to do this. Anyone have anything like this happen before?
