I am installing my ASP pulley, I have it about 80% on and now it is just spinning the crank shaft and I cant make it tighter. Is there any trick that I am missing here?

 

You need to jamb up the flexplate with something to keep the engine from spinning. I've dropped the starter and used a BIG screwdriver going through a hole in the flexplate before. You can also take the little inspection cover off the transmission bellhousing and jamb a big extension or bar up in there to keep the engine from spinning.

 

Ok, got it, just installed. Thanks for the help!
