Do the YB and pinto use the same big end bearings?

 

As far as im aware, the pinto and cossie both use the same bearings dimensionaly but the cossie uses a superiour finishing material to cope with the extra loads placed upon it.

In fact I know im right regarding them being the same size as I just remember a mate of mine built up a standard cossie bottom end ie crank and block to use with a pinto head and he used pinto shells.

Personaly i'd go for gen Vanderval bearings if rebuilding a cossie lump....GGR stock them in their ebay shop in most sizes.

Stu.

 

as above go my bearings of matt lewis very good price
