I have now lost my second engine and third cam in a Ford 460. All failed in less the 100 miles. Lifter ground down and cam lobe.Not sure what I am doing wrong.
First Engine had Comp Cam and Lifter. Wiped out 6 lobes and lifters in 60 miles along with the crank.
Second engine was a Ford SVO short block, Ford .588I,614E cam with Ford SVO lifters. Heads are SCJ Alumimum with Sharpe roller rockers. Spings are 130#closed, 375#open.
Used the
oil additive for breakin and moly on the lobes and lifters. Primed engine and ran at 1500 RPM for brake in.
2 years, 3 engine pulls and less than 200 miles on the car, Frustrated!
Do I need to go to smaller cam, lighter springs, roller cam/lifters?
Ideas?
