Do you want to increase the performance of your mini and save money? Put some sweat equity in your rebuild. If your gearbox is still good why not use it. With this kit and some items off your old engine your set to go.

This A+ block had its oil galley and core plugs removed. The block was hot tanked, Overbored & cross-hatch honed to 1380cc. Oil galley and core plugs replaced, new bearings installed and a NEW CAM6232 crankshaft and Vernier adjustable timing chain were installed.
