Ok hears the deal, I have a 93 F-250 with a blown 5.8 liter and automatic
I have a wrecked 86 F-150 with a 300 and a standard tranny in it. I pulled the 300 today and can see that it will bolt up to my F-250 tranny and the flywheel bolts line up But theres a weight on the 5.8 flywheel so I am assuming it is an externaly balanced engine. Is the 300 internaly balnced or external?

Can I remove the weight from the 5.8 flywheel and use it?

Budget is extrememly tight and I really need to get it running as I should be getting called back to work in the next two weeks or so.

Ok the info I have gathered so far tells me the 300 is internally balanced and the 5.8 is externally balanced.

Ok problem solved.
Step one
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.

Step two
Put the 5.8 flexplate in the lathe, nasty vibration at less than 1000 rpms

Step 3
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
