Was wondering if I can take my olds 350 motor and install a 400 crank to turn it into a stroker motor? I know you can do this to chevy motors (sorry I know this is a bad word) but can you do it with olds motors as in a previous letter by eighttime am looking to add power to my motor, was originally thinking stroker until I was told can't do it with an olds because they didn't make a 400 and low and behold they do! Still tossing around the idea of a big block too.
Question 2 went to add oil while it was running and the oil burped back up through the tube, I know it has a bigger oil pump in it could this cause it? Or could it have been that the pcv valve was in the valve cover but was not getting vacuum or some other problem?
Question 3 It has a 3 speed auto in it that doesn't kick down when you stomp on the throttle, shouldn't it kick down? And what could be some causes?
