I put this engine together in 2011, and have approx 450 hours on it. 516” BBC, AFR 305’s, approx 9:1, Straub has roller cam.
Down on power and sounded like it lost a cylinder. Tore it down and found 4 sets of tie bars broken off.. . One spun and took out #2 intake lobe.
Obviously this didn’t happen all at once, but more importantly, WHY did it happen? Any insight or ideas are welcome.. I’m dumbfounded.
