I see the windage tray bolts and would just like to add that the flat GM tray will fit inside a stock Chevelle oil pan too. Our car had one most of its life. One thing with the engine disassembled, it is easy to measure to see if the block has ever been decked.

I should add, I do have the original oil pan for the engine as well.

I think you will find that the 396 and 427 were internally balanced from the factory. The 454 had the weighted balancer and flywheel for an external balance.

Hmm, interesting Keith. I was not aware of that. Thanks for the info. Now if I could only sell this thing...
