Re: engine swap questions
Ok problem solved.
mount the 300 flywheel in the lathe and spin it up. I figure I had it going 2000 rpm's and no vibration, it did take it a while to stop though.
Put the 5.8 flexplate in the lathe, nasty vibration at less than 1000 rpms
remove the weight from the flex plate. put it back in the lathe.
3600 rpms an as smooth as a swiss watch. Well maybe not a swiss watch but as smooth as a timex which is close enough in my book
