What info are you looking for? I was looking for info myself on them a few days ago. I have a couple of them that were taken out of old grain trucks. Every thing I found about then says there are pretty much boat anchors as a whole. Here is what mortec says about them. Some good parts in them yet though. If you have some good info on them or find anything, I would like to know also. Please post what you find.

We are asked about the 366 BBC "tall deck" truck engines often. Unfortunately they are not worth using as a performance motor. Safe overbore is .060" and that doesn't make much. They can be stroked but then you can't find pistons to match "off the shelf" and so custom pistons are required. You can "harvest" the heads, oil pan, valve covers, crank and rods from them to use on another larger bore Mark IV BBC. Otherwise, don't waste your time or money. The 366 makes a good low power heavy duty truck mule engine or an excellent boat anchor
