Agreed, as long as the driver does not rev the snot out of it they would be fine. Street car and 6500 RPM and it would probably never bother. Took 7500 rpm wide open throttle spped shifts to spin my #5 rod bearing. NOT you average street driving. LOL!!! As far as clearance issues, I ran a bolt w a washer on my last few engines and clearanced the pump just like jbc426's photo. So far, so good
