Buick Engine Quality

Most rebuilt Buick engines are just that, rebuilt. Our Buick remanufacturing line builds to IMPROVE not just REPLACE! All parts in our high quality Buick performance engines (long blocks, short blocks, big blocks & small blocks) meet or exceed all the Buick original specifications, and most of the time are purchased from the same suppliers who supply Buick!

All the moving parts in our Buick 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 Buick Engine line has achieved one of the lowest breakdown rates in the world - Below 1.5% breakdown rate

We keep a large inventory of Buick remanufactured engine blocks mostly for passenger cars, light trucks, pickups and some marine applications. Most of our Buick engine supply is ready for instant freight.
