We restocked an improved Small Block motor. You can't go wrong at 5 bucks each. These turn around 20,000 rpm. The new version is an FK130 based motor. Some people did not like the enclosed can on one end, making gear pressing difficult. This new motor has bushings on both ends that allow the shaft through, problem solved. This 12 volt motor should last longer than the old model. https://www.slotcarhotrod.com/product-page/small-block
