    Default 2.3 crankshaft

    When should the crankshaft be changed in a 2.3 ford ? I have heard they should be changed after each year of racing. Have one that has 10 races on it. It was new last year when installed.

    there are a lot of factors.
    is the crank lightened? is your rotating assembly balanced? how many rpm's are you turning?
    i use a stock weight crank with a fully balanced rotating assembly and turn 7,500-7,800 running 24-30 races a year.
    crank has 4 seasons on it and is still in good shape.
    good machine work is key .

    i agree 100% exfordtech , i have never really seen a well balanced crank break , usually oil related failure.....BTW , we found the merkur turbo cranks are practically indestructible......

    The best time to change a crank is after it starts to crack but before it breaks. lol. I inspect crankshafts after every season. The engine I run has 65 races on the crank over the course of 3 seasons (stock crank only slightly lightened but well balanced). Asphalt 3/8 and 4/10 mile tracks spinning 8500 rpms. Good machine work and attention to detail equals long life and less money in the long run.
