At precisely 5800 rpm my fe hits a wall and loses power. Feels like a rev limiter but worse. I have a hydraulic roller cam from comp cams. I thought it was my old dual point distributor so I bought msd distributor coil and box. Same thing at at 5800 rpm. The engine builder told me that the flat tapped valve springs that were on the heads originally were fine so he did not install new springs. He says it's not related to the springs but still has no answer for me. The old springs were about 10 years old on a non running engine so several valves were open for that long. Could these springs create this 5800 rpm fall off? What does valve float feel like?
