331 stroker

  1. 331 Stroker Tick (or rattle) when engine is cold

    All Ford Techboard
    Any help is greatly appreciated! I've got a 65 mustang with a 331 stroker that has developed an odd tick or rattle that only occurs when the engine is warming up. It sounds pretty much identical to a lifter tick, except a bit louder. The odd part is that it will only rattle at 1200 rpms...
