Dorman 690-025 pilot bushing

Yup, I've had good luck with the Magnum bearings too, as long as it's not a '67 and earlier 273 or slant 6. On those early cranks, I've had to run a hone in the end of the crank and then cut down a bushing for them. I used an adjustable reamer to chuck the bushing on, and then put it into my drill press to turn it. Some course sand paper was all it took to reduce the diameter enough to get it to fit into the crank. Don't cut it too much. You still want to have a slight interference fit so it doesn't spin in the crank hole. Of course, if you have the crank out of the block, you can always have a machine shop make the hole the correct diameter for a stock bushing.
