Is the support plate that I put between
the block and the engine stand mount
Probably not if the big front plate goes to
the top of the block.
These were the only block modifications I needed for
the support plate. I only had to grind off about one
sixteenth inch off the edge of the main bearing pads.
Look carefully at the main bearing bolt holes and you
will see the transfer screws I used here.
One more thing, the engine stand motor mount adapter
wasn't meant to bolt to main bearing pads so grind off
anything that gets in the way!
Necessary changes to the front of the block?
You found out what was needed when you first fitted the blocks
together. Now is the time to get any grinding done. In my case it
actually took very little.
