Message: [QUOTE="Hotrodtractor, post: 1366552, member: 25"] Cyclical stress caused fatigue until the an imperfection allowed a crack to form and repeated use opened it up. To minimize this type of failure it means you need to reinforce the block from flexing as much.... ie girdle, bedplate, filler, etc... You have to remember you have been running this thing at double the rated power for 100K miles. This happens. You crank up the power, you shorten the life. Is a 100K mile failure rate acceptable? If not - turn down the wick or decrease block stress as listed above. If its acceptable - toss in another motor and rock on. [/QUOTE]
