Thanks for all the replies guys. This is all what I kinda figured, but maybe wasn't ready to accept. It has been over a decade since I have torn down and did a basic rebuild. I may take it to a machine shop just to get everything checked out.

I did have a question about the external balance. I don't have the original torque converter, so I don't know about what weight to apply to a new converter.
All of the external balanced big blocks I have used in the past had the converter with it. If we swapped converters after that, we knew what weight to add to the new converter.

Anyway, Thanks again for the bench racing/building session!

It does spin easy. Even by hand, the short block spins freely. My next day off is next week, I will pull the caps and post pics. Connecting rod ends are NOT discolored.



If none are spun and the crank looks good put it together and run it, or put bearings and rings in it and run it. If it was oil starved for significant time you will see it, and it probably wouldn’t spin easy.

I'll take off the caps and inspect. I will also post some pictures next week when I tear it down, thanks

Take a good look at the top and bottom bearings on both the rods and Mains twocents
if any of the rod bearings fall out of the rod caps replace them now so they won't spin later, same thing on the main bearings, if they are loose in the caps replace them. scope wrench up

I seem to recall the weight put on the convertor was 50 grams. I’m sure the number is floating around in cyberspace.


I want my fair share

That sounds familiar. Years ago we were able to buy a weight from somewhere (don't recall) and welded it on a new neutral balance converter for an external balance engine we used. Were these weights in the same spot on the converter on every rotating assembly?

Weights and location varied depending on application.

B+M makes a weighted flex plate for external balanced engines so you can use a neutral balanced converter. It's a lot easier to use than trying to get the weights welded on in the proper place and proper weight. The last one I bought was several years ago from Summit Racing. At the time I paid $100, they're probably $150 now.

I saw this flexplate at mancini.

So, to clarify, you would use this flexplate and that eliminates a need for a welded weight on the converter, correct?
