I have used them before. they are good for otherwise stock motors. once you do anything like over bore, high comp, cam, the motor will rap like a black kid on a friday.

but for a stock motor they are cheep noticible power.

you will need a flywheel puller, new stator cover gasket, and be shure to be real careful re-instaling them 8mm bolts that hold on the stator cover. them things snap and or strip way to easy.
