I have the same one the little expander broke the first time I used it and had to but a new one after that it worked great just a heads up if you need it again lol. I didn't see where you posted what cam are you using? Is it a roller cam or flat? You have the specs on it?
It’s just a stock 5.2 cam. It’s a Magnum so factory roller. My original one had a couple wear spots I didn’t like on a few lobes. I found a guy on Fakebook who built a 390 stroker so I bought his oem cam.
