Chevrolet 216 - engine bearings

[motto (RIP)]

The main bearings were shells from the start although they were shimmed.
As far as I know the mod to put shells in the big ends was an after market arrangement.
Unfortunately I don't have the dimensions to hand that you require. I'm sure I have the big end bore diameter for shell installation somewhere but that is possibly on board the truck in the UK.
The shells are quite thin and are available from Jim Carter Antique Truck Parts in various under sizes.
Sorry I can't help you more Richard

I've had a look through my 216/235 bits and pieces and have not found any of the dimensions requested.
I did find a set of new big end shells for these engines which means that at some point I may need to have a set of rods bored to take them. The shells are in a packet labelled Michigan 77 and the shells are marked CLEVITE.
I to need to know the bore diameter of the connecting rod big end for proper fitting of these shells.
