392 Hemi


I have a '58 Imperial 392 in my '67 Belvedere. The car was a factory 4 speed and retains all the standard transmission items. What I wanted to know is will the 392 accept a pilot bearing? I read somewhere a long time ago that since these engines only found their way into the big luxury cars in their latter days that they didn't bother milling out the crankshaft for a pilot bearing since they were all automatics. Just wanted to confirm this.

The problem will be that the crank flange rides way out from the block.
However the bolt holes will align with a small block bellhousing. However, the alignment pins are located differently.
Buy an adaptor kit that uses a small block bellhousing and you should be able to make it work.
You will have to use a 426 flywheel and clutch.
I have built a couple of these set ups using the kit from T.R.Waters and have had good results.
This kit comes with a pilot bearing, and a piece to put it in.
Had to make my own hydraulic setup for the clutch so there may be some adapting there in your Belvedere.

So, I guess that means nobody knows for sure...If I were building a drag race Hemi it wouldn't be too much of an issue to run the crank down and have it drilled out for a pilot bearing. I was wanting to know whether they came like that from the factory or not.
