Thread: why do i keep going through motors like candy?

balancing could destroy everything in the engine. To eliminate your end, I would run stock pulley, throw all the supporting mods you want. Drive it. Change oil and filter after 500miles imo as you dont know whats been in that engine. Dont beat it. Drive many more miles. Drop pulley. If goes boom, YOU DID IT!

on your "rebuilt engine" did they resize the rods/ change bolts ?
