So last week after some playing around on the highway with a few friends, I put a few cracks in my high mileage stock flexplate.
I guess higher compression,3000 stall,150 shots and awd drive kinda beat that thing up alittle.

 

So now thst you pulled the powerplant, what are you dropping in?

 

Looks like your bolts possibly backed out a little??

 

Bolts where loose a little from having no pressure any longer. The flexplate had 130,000 miles on it behind close to 11:1 engine that had quite a few bottles at 150 ran through it. It's back together and back to N/A for awhile

 

I never understood why GM went with just three bolts. I guess it wasn't designed with 450+ rwhp in mine. Seems like 6 would be cheap insurance.

 

Thats why the 80E has 6 bolts...
