| The original AM&P "Mule" 525 lb ft of torque and 425HP $5,500 turn key carb to pan,damper to flex plate |
Our first mule was built for the purpose of testing various some 455 specific parts such as a
crankshaft scraper, different oil pump assemblies etc.
After customer requests for a price on it, we decided to sell it and build another.
The "Mule" was such a hit on its economical price and "free core" we have decided to build them
as parts become available to do them at a price discounted form our regular crate engines.
Please note that these engines will have blocks that do not clean up at .030, cranks that wont
clean up at .010 -.010, and may have some really good used parts. To keep the price down a
carburetor and distributor must be furnished
