Hi guys,

I'm almost ready to re-install my 1956 235 in my 59, and it's time to address the broken off mounting bolt. On the driver's side, the front mount has two bolts that hold the mount to the engine. At some time in it's life, the engine had the bottom bolt break off flush with the block. The Some previous owner then decided it would be a good idea to try and drill it out. Apparently drilling in the center wasn't a good idea to him, so he drilled a 1/8" hole where the bolt threads meet the block. I know this hole is going to stop me from being able to easy-out the bolt.

Now my question, is it possible to simply leave the broken off bolt in the hole, and drill/tap the hole that has been started? If I do this, the threads will be half block, and half bolt. I know there is enough play in the rubber bushing that 1/8" off on the mount won't make a huge difference. Or do I have any other options outside of running just one mounting bolt like the previous owner did?

Thanks, Vince
