Hi All,

Finished my restore three years ago and been driving without issues. The engine is a 78 360 75k on it. I replaced all pumps and seals but left the piston, and crank assembly alone. I had the heads redone and replaced timing chain, etc.
The 904 is stock, I adjusted the bands and replaced the filter and drained everything including the torque converter.

I installed a B and M flex plate and verified the part number before posting this. Also I have dropped the transmission to check the plate and it looks fine, its still mounted, but I can see most of it.

I think I have had now for a while some piston slap that would disappear after warm up, so now I'm not sure if this sound is related.

So take a listen, hopefully I have copied this URL correctly.

If you can see in the video, the noise is most noticeable inside at the trans hump. I can also feel the knock on the passenger side motor mount.
