AC 426

I’m working with an AC 426 and I have a few questions. How much hp will stock connecting rods safety handle? Is there any glaring weak points I need to address when you start pushing theses engines? |

Heat treat the rods to 43 or they will break |

Definatily heat treat rods and get good rod bolts, arp or similar. Running 800-900 hp on big pin rods no problems yet. |

Thanks for the input do you have any suggestions on a company to treat the rods and I assume to resize them from distortion? |

I have heard of that being done but not particularly with the AC 426 and I wouldn’t know where to begin with a project like that. Any suggestions would be greatly appreciated. |

Not much to worry about up to 1800hp with hardened, big pin rods. Replace rod bolts with high quality ones every other time apart. Worry about the cylinder head. 2nd Max Simpson. |

I may be interested in those rods what is the best way to contact you. Also can a P pump be mounted without the use of an aftermarket timing cover? |

Yes. Just have to do some machine work to front plate and have to cut the lower inner mounting ear off the pump |
