AMC Engine Quality
Most rebuilt AMC engines are just that, rebuilt. Our AMC remanufacturing line builds to IMPROVE not just REPLACE! All parts in our high quality AMC performance engines (long blocks, short blocks, big blocks & small blocks) meet or exceed all the AMC original specifications, and most of the time are purchased from the same suppliers who supply AMC!
All the moving parts in our AMC remanufactured engine are NEW. Be cautious of other engine remanufactures using used, broken, re-machined or returned parts!
Due to our precise re-manufacturing standard, the AMC Engine line has achieved one of the lowest breakdown rates in the world - Below 1.5% breakdown rate
We keep a large inventory of AMC remanufactured engine blocks mostly for passenger cars, light trucks, pickups and some marine applications. Most of our AMC engine supply is ready for instant freight.
