I ran my rebuilt 440 up last night . all was good. shut it down and then restarted it . We heard a pop and then shut the motor off . Tried to restart it we had no spark. Turned out that the cam was not turning . We removed the timing cover and found the cam bolt broke off and the dowel pin sheared off as well.
The motor is .30 over ,440 source heads. Cam is a comp cam .460 intake lift almost stock.we did the pre oil and had oil running out the rockers both sides. oil pressure was 50 on my gauge.
whats your thoughts ? cam seized ? bad cam bearings ? or just bad cam bolt ?
whats next ? new cam and bearings ?can i get the dowel pin out that broke ?
Thanks
